Finite Element Modelling of microscale and macroscale on deformation of composite material

Performance prediction is an important aspect in confirming the correct design specification of composite materials. Finite Element Modelling (FEM) approach enables to calculate stress and strain components of a structure for more realistic strength predictions. In this study numerical simulation is perform using FEM method to simulate composite materials through tensile test at micro and macro level. The geometric for tensile test were according to ASTM D3039 for GFRP and CFRP. Micromodelling of composites were simulated based on theory of Representative Volume Element (RVE). It is found that RVE able to predict deformation and mechanical properties extraction of composite in unidirectional.
