Implementation of Stress Loading Repetitive Unit Cell Finite Element Model

Abstract

Finite element modeling of repetitive unit cell (RUC) with imposed periodic boundary conditions (PBCs) is a widely used approach for not only determining effective macroscopic material properties but also studying the damaging mechanism of composite materials. In this paper, a stress loading RUC model with PBCs was developed. The procedures for obtaining the effective homogeneous material properties are presented in detail. Thus the proposed model can be easily reconstructed by interested readers.
