Description

Technical Field

[0001] This application relates to the field of flexible structure technology, and in particular to a method, apparatus, computer equipment, and storage medium for simulating the deformation capacity of flexible multilayer structures. Background Technology

[0002] Today's electronic technology is constantly evolving towards greater intelligence and user-friendliness. Devices designed based on traditional electronic technology suffer from drawbacks such as poor deformability, susceptibility to brittle fracture, and extremely poor biocompatibility, making it difficult to meet people's higher demands. However, the emergence of flexible electronics technology is gradually breaking the deadlock in the development of electronic technology. Its core idea is to integrate high-performance circuits with flexible substrates, enabling electronic devices to have characteristics such as large deformability, light weight, and reconfigurable functions.

[0003] The combination of inorganic thin films and flexible substrates enables electronic devices to bend, representing one of the earliest technologies achieved in flexible electronics. Therefore, bending deformation is one of the most fundamental and important deformation capabilities of flexible electronic devices. The bendability of a device is often measured by the minimum radius of curvature it can withstand; a smaller radius indicates a stronger bending capability.

[0004] Furthermore, typical flexible electronic system designs require the integration of several different materials within a single platform. Therefore, flexible electronic devices are generally multilayer structures composed of multiple thin films and a substrate. When flexible devices or structures are subjected to frequent bending or stretching, harder materials are prone to cracking, while severe stress concentrations easily occur at hard / soft interfaces, leading to layer peeling and separation due to mismatched mechanical properties. Placing vulnerable thin film layers in neutral layers during structural design provides excellent protection for these layers. Therefore, understanding the bending deformation capability boundaries of flexible multilayer structures is crucial. However, relying on actual testing to detect the bending deformation capability of flexible multilayer structures is not only inaccurate and ineffective but also costly and inefficient. Summary of the Invention

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for simulating the deformation capacity of a flexible multilayer structure according to an embodiment of the present invention.

[0053] In this embodiment, the simulation method for the deformation capacity of flexible multilayer structures includes:

[0054] Step 100: Establish a planar geometric model of the flexible multilayer structure.

[0055] For example, a planar geometric model corresponding to a flexible multilayer structure is established in the simulation system.

[0056] Specifically, the simulation system can use ABAQUS simulation software.

[0057] ABAQUS is a powerful finite element method (FEM) software for engineering simulation, capable of solving problems ranging from relatively simple linear analyses to many complex nonlinear problems. ABAQUS includes a rich library of elements capable of simulating arbitrary geometries and a wide range of material models to simulate the properties of typical engineering materials, including metals, rubber, polymers, composites, reinforced concrete, compressible hyperelastic foams, and geological materials such as soil and rock. As a general-purpose simulation tool, ABAQUS can solve numerous structural (stress / displacement) problems and simulate many other engineering problems, such as heat conduction, mass diffusion, thermoelectric coupling analysis, acoustic analysis, geotechnical analysis (fluid permeability / stress coupling analysis), and piezoelectric analysis.

[0058] Step 110: Set the structural properties of the planar geometric model.

[0059] It is understandable that the structural properties of each layer of the planar geometric model are set to match the characteristics of the actual flexible multilayer structure.

[0060] Step 120: Establish the carrier model.

[0061] Understandably, flexible multilayer structures need to be attached to a carrier when they bend and deform. Therefore, a carrier model is established to simulate the state of the flexible multilayer structure when it bends and deforms.

[0062] Step 130: Obtain the deformed model of the planar geometric model attached to the carrier model.

[0063] For example, the bending deformation of the planar geometric model attached to the carrier model is observed and calculated to obtain the deformation model, so as to simulate the deformation capacity of the flexible multilayer structure.

[0064] The aforementioned simulation method for the deformation capacity of flexible multilayer structures involves establishing a planar geometric model of the flexible multilayer structure; setting the structural properties of the planar geometric model; establishing a carrier model; and obtaining the deformation model of the planar geometric model attached to the carrier model. This method simulates the flexible multilayer structure by bringing the planar geometric model of the flexible multilayer structure into contact with the carrier model during the simulation to calculate the deformation model of the flexible multilayer structure. The calculation is accurate and effective, while reducing costs and improving detection efficiency.

[0065] In another embodiment, establishing a planar geometric model of the flexible multilayer structure includes establishing a planar geometric model based on the in-plane geometric characteristics of the flexible multilayer structure or simplifying the three-dimensional model of the flexible multilayer structure to obtain a planar geometric model. It is understood that when directly establishing a planar geometric model based on the actual flexible multilayer structure, the thickness dimension can be ignored, and only the in-plane geometric characteristics of the flexible multilayer structure need to be established. When the original geometric model is imported from external software, operations such as mid-surface extraction and Boolean operations can be used to simplify the three-dimensional model of the flexible multilayer structure to obtain a planar geometric model.

[0066] Please see Figure 2 and Figure 3 , Figure 2 and Figure 3 This is a schematic diagram illustrating the simplified planar geometric model of a flexible multilayer structure according to an embodiment of the present invention, obtained from a three-dimensional model.

[0067] In another embodiment, setting the structural properties of the planar geometric model includes setting one or more structural properties such as region selection, material settings, thickness, and reference surface rotation angle. Specifically, in the ABAQUS simulation software, the Composite Layups setting is performed in the Part subcommand of the planar geometric model. The number of Plies (layers) is set according to the actual number of layers in the multi-layer structure. For example, if the multi-layer flexible structure is a 3-layer model, from bottom to top, layer 1, layer 2, and layer 3, then the number of Plies needs to be set to 3. For each Ply, the structural properties that must be set include region selection, material settings, thickness, and reference surface rotation angle. Region selection is done by selecting the corresponding graphic for each layer in the planar model of the multi-layer structure; material properties and thickness settings are determined according to the actual model; the reference surface rotation angle is generally set to 0 degrees; the remaining parameters can be set using the default settings of the simulation software. In addition, sometimes it is necessary to set the reference plane and its offsets. If the plies are arranged in order from bottom to top, the offset method should be selected as the Bottomsurface option, otherwise select the Topsurface option.

[0068] In another embodiment, establishing the carrier model includes establishing a cylindrical rigid rod carrier model. Specifically, based on computational requirements, a discrete rigid body or analytical rigid body type is selected, and multiple cylindrical structures with different radii are established to serve as carriers for the flexible multilayer structure. It is understood that establishing multiple carrier models with different radii is to allow the planar geometric model corresponding to the flexible multilayer structure to be attached to carrier models with different radii, in order to test the range of bending deformation capabilities of the flexible multilayer structure.

[0069] Please see Figure 4 , Figure 4 This is a schematic diagram of a cylindrical rigid rod carrier model representing an analytical rigid body and a discrete rigid body according to an embodiment of the present invention, wherein... Figure 4 The left side shows a schematic diagram of a cylindrical rigid rod carrier model of an analytical rigid body. Figure 4 The right side shows a schematic diagram of a discrete rigid body cylindrical rigid rod carrier model.

[0070] For example, obtaining the deformed model of the planar geometric model attached to the carrier model involves using the bottom surface of the planar geometric model as the slave surface and the surface of the carrier model as the master surface, establishing contact between the planar geometric model and the carrier model. Specifically, this involves tangential, frictionless surface-to-surface contact between the planar geometric model and the carrier model. Specifically, a dynamic or static method is used to obtain the deformed model of the planar geometric model attached to the carrier model. Understandably, static methods are generally preferred for solving the problem. If the static method fails to converge, a dynamic method can be attempted. For rigid cylinders, the boundary conditions can be set in a uniform and fixed manner, i.e., setting a reference point for the rigid body and applying full constraints to it. However, for flexible multilayer structures, the application of boundary conditions is not uniform and can be set according to actual needs.

[0071] Please see Figure 5 , Figure 5 This is a schematic diagram of the contact between a planar geometric model and a carrier model according to an embodiment of the present invention.

[0072] Please see Figure 6 and Figure 7 , Figure 6 and Figure 7 This is a simulation diagram of the deformation capacity of a flexible multilayer structure according to an embodiment of the present invention. The planar geometric model of the flexible multilayer structure is attached to the carrier model, and the bending degree and deformation effect of the planar geometric model under the attached state are calculated to obtain the deformation capacity of the flexible multilayer structure.

[0073] Please refer to Table 1, which shows the method for applying boundary conditions in the bending analysis of square-type flexible multilayer structures.

[0074] Table 1. Methods for applying boundary conditions in the bending analysis of square-shaped flexible multilayer structures.

[0075]

[0076] Understandably, by using dynamic or static methods to calculate the deformation field of the planar geometric model attached to the carrier model, the bending deformation capacity of the flexible multilayer structure can be obtained.

[0077] It should be understood that, although Figure 1 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0078] In one embodiment, such as Figure 8 As shown, a simulation device for the deformation capacity of a flexible multilayer structure is provided, comprising: a planar geometric model establishment module 200, a setting module 210, a carrier model establishment module 220, and a calculation module 230, wherein:

[0079] The planar geometry model creation module 200 is used to create planar geometry models of flexible multilayer structures.

[0081] A planar geometric model is established based on the in-plane geometric properties of flexible multilayer structures;

[0082] or,

[0085] The setting module 210 is also used to set one or more structural properties of the planar geometric model, including region selection, material settings, thickness, and reference surface rotation.

[0086] The carrier model creation module 220 is used to create a carrier model.

[0087] The carrier model creation module 220 is also used to create a cylindrical rigid rod carrier model.

[0088] The carrier model establishment module 220 is also used to select discrete rigid body or analytical rigid body type and establish multiple cylindrical rigid rod carrier models with different radii.

[0089] The calculation module 230 is used to obtain the deformed model of the planar geometric model attached to the carrier model.

[0090] The computing module 230 is also used for:
