Computational Study of Compressive Mechanical Response in Two-dimensional Cellular Solids under Microstructural Control

A new computational mechanics model is proposed to describe the compression response of two-dimensional cellular materials with consideration of microstructural development. In this modeling, processing conditions to fabricate cellular materials are taken into account as a cell-growth mechanism. Representative volume elements (RVE) are generated by the phase-field model. Numerical simulations of compressive deformation are performed by finite clement analysis for the selected RVE. The cell size distribution especially affects on the limit stress and the densification process.
