Drop-Weight Impact Response Measurement and Prediction for Quasi-Isotropic Carbon-Epoxy Composite Laminates
Quasi-isotropic carbon-epoxy plates are subjected to both out-of-plane impact and quasi-static indentation. Post-mortem damage inspection is carried out by optical microscopy and ultrasound scanning. Two continuum damage mechanics models are used to predict the ply damage. Delamination failure is included through a contact formulation. Self-contact must be enabled to prevent excessive ply penetration. Even though some material properties are estimated from literature, a reasonable agreement between the experiment (static and dynamic) and prediction is obtained.
