Influence of Different Modeling Strategies for CFRP on Finite Element Simulation Results

Influence of Different Modeling Strategies for CFRP on Finite Element Simulation Results

Numerical simulation is used to predict the behavior and response of carbon fiber reinforced plastic (CFRP). Sometimes zero thickness of interface layer is introduced into the numerical model to investigate the inter-layer behavior like delamination. To investigate the influence of critical volume-t...
