Résumé

An ultimate failure criterion is proposed to predict strength and failure mode of composite laminates under a tensile loading. The upper bound theorem of limit analysis is used to approximate the ultimate load capacity for composite laminates and identify different collapse mechanisms. The present model is used to predict failures modes in plies and interfaces. Experimental results are presented and a comparison with theoretical predictions is made. Tests have been performed on several specimens of various lay-ups. A thickness effect on delamination is observed as well.
