The Finite Element Method for the Elasticity of Micro-pores Material

Abstract

This study aimed to investigate micro-pores' impact on the elastic energy of materials using open-source simulation. The finite element method analyzed linearly elastic, homogeneous, and isotropic materials. The domain is modeled as an isotropic elastic material with a constant thickness and is treated as a two-dimensional rectangular plate. The positions and diameters of the micro-pores were varied. The results indicate that the position and diameter of the micro-pores within the domain significantly influence the magnitude of elastic energy. Larger pore diameters correspond to higher values of elastic energy. Additionally, the elastic energy value of the micro-pores remains relatively constant, though it is smaller when the pores are located at the ends of the material. This suggests that the elasticity at the end of the material is reduced due to pressure-induced movement. Furthermore, varying the diameter of the micro-pores leads to more noticeable changes in material shape, with larger diameters resulting in more pronounced alterations.
