The paper is devoted to the modeling of porous silicon matrix, the study of its mechanical properties in the Ansys virtual design environment at different indices of porosity and comparison with the experimental data taken in the laboratory [3]. Testing in software systems using the finite element method is universally used in various applied industries: construction, medicine, materials science. In this paper, we tried to use Ansys Material Designer to simulate the microstructure of porous silicon with different percentages of pore filling. After constructing the microstructure, we used this model in the Static Structural module to investigate the mechanical parameters of a sample made of a previously calculated material. The mechanical properties of the porous structure were simulated using the Static Structural module.
