Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as figure 2 Shown, the virtual modeling method of particle reinforced composite material of the present invention, based on ABAQUS platform and python language, comprises the following steps:

[0025] Step (1), the determination of the three-dimensional geometric size of the material: assuming that a number of spherical particles are uniformly distributed in a cube with a side length of 9i, the side length of 9i is divided into 9 equal parts, and each division point is a center of gravity of a spherical particle, then a There are 10 spherical particles evenly distributed on the side. The percentage of the volume of spherical particles to the volume of the whole cube is the volume ratio of the material. Let the volume ratio of the material be ρ. Calculate the volume ratio of the material by controlling the diameter of the spherical p...

Abstract

The invention discloses a virtual modeling method for a particle reinforced composite material. Based on an ABAQUS platform and the python language, the three-dimensional geometrical size of the material is determined; in the three-dimensional geometrical modeling process of the particle reinforced composite material, a virtual grid method is adopted, only one spherical particle is distributed at the common vertex of adjacent grids, and the center of gravity of the particle is the grid vertex, wherein, in a cube, the spherical particles are reinforced phases, and the other parts are collectively called a substrate; script codes recorded by the ABAQUS are adopted for arrangement and compilation, a Python automatic modeling calculation script is formed, the spherical particle distribution rule generated through programming is input into a script file in a coordinate form and directly submitted to an ABAQUS kernel for operation, a research variable is set as a function variable in the Python script, and the geometrical model of the corresponding particle reinforced composite material can be generated by selecting different volume fraction ratios. The virtual modeling method depends on no CAD software except for the ABAQUS, and the dependence on the software except for the ABAQUS and the necessity of the software except for the ABAQUS are greatly reduced.

Description

technical field [0001] The present invention relates to the field of computer three-dimensional virtual modeling, specifically a method for virtual geometric modeling of particle-reinforced composite materials, especially a method for three-dimensional geometric modeling of particle-reinforced composite materials based on the ABAQUS platform and python language . Background technique [0002] ABAQUS is a set of powerful engineering simulation finite element analysis software with powerful nonlinear analysis and calculation functions, which can solve linear and complex nonlinear problems. Because of ABAQUS's excellent analytical ability and reliability of simulating complex systems, ABAQUS is widely used in industries and researches in various countries. It is one of the ways of secondary development of ABAQUS to realize the whole finite element modeling process by writing the kernel script. ABAQUS software itself has a good application programming interface, and it is an e...
