Embodiment Construction

[0079] Embodiments of the present invention provide a composite material finite element modeling method, system, and storage medium. The present invention introduces the concept of the overall domain, and avoids direct modeling of the matrix of complex spatial configurations through the finite element grid division of the overall domain. Various meshing problems caused by finite element meshing are achieved, and the independent meshing of the enhanced phase geometry model and the overall domain geometry model is realized, which reduces the correlation between the two meshes The mold accuracy is controllable, which reduces the time cost of simulation calculation under the premise of ensuring the accuracy of composite material finite element modeling.

Abstract

The invention relates to the technical field of computer-aided engineering, and discloses a composite material finite element modeling method and system and a storage medium. The composite material finite element modeling method comprises the following steps: generating a reinforced phase geometric model and a global domain geometric model corresponding to a composite material; assembling the reinforced phase geometric model into the global domain geometric model to obtain a composite material geometric model; respectively carrying out finite element mesh generation on the reinforced phase geometric model and the global domain geometric model in the composite material geometric model to obtain an initial composite material finite element model; and sequentially carrying out node degree-of-freedom coupling processing on the space overlapping areas of the reinforced phase grid units and the global domain grid units in the initial composite material finite element model to obtain the composite material finite element model. According to the method, on the premise that the finite element modeling accuracy is guaranteed, the calculation cost is reduced, and the modeling time cost is saved.

Description

technical field [0001] The invention relates to the technical field of computer aided engineering, in particular to a composite material finite element modeling method, system and storage medium. Background technique [0002] A composite material is a kind of material composed of reinforcing phases and matrixes with different properties. Through the complementarity and correlation of the properties of each component, comprehensive properties that cannot be achieved by a single component material can be obtained. Since the performance of composite materials is closely related to the shape, content, distribution and other factors of its component materials, the macroscopic properties of the material can be improved by adjusting the microscopic configuration of the component materials. [0003] Finite element simulation is an important analysis method to explore the influence of microscopic configuration changes on the macroscopic properties of materials. For composite materia...
