STUDY ON LOW-VELOCITY IMPACT BEHAVIOR AND RESIDUAL PERFORMANCE PREDICTION OF CFRP T-JOINTS
J. Zhou, China; C. Zhang, China
Current methods that employ multiple models to assess the mechanical properties of composites exhibit certain limitations. This study develops a combined FE analysis method, based on stress failure criteria and stiffness degradation theory. It transfers element damage states between models, avoiding traditional method inefficiencies and errors in multi-model information transfer.
