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, system and storage medium. The composite material finite element modeling method includes: generating the corresponding reinforced phase geometric model and the overall domain geometric model of the composite material; assembling the enhanced phase geometric model into the overall domain geometric model to obtain the composite material geometric model; The enhanced phase geometric model and the overall domain geometric model are divided into finite element meshes to obtain the initial composite finite element model; in turn, the spatial coincidence area of ​​the enhanced phase mesh unit and the overall domain mesh unit in the initial composite finite element model is calculated The node degrees of freedom are coupled and processed to obtain the finite element model of the composite material. On the premise of ensuring the accuracy of finite element modeling, the present invention reduces calculation cost and saves modeling time and cost.

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...
