Keywords: composites, interlaminar stress, cohesive elements

Experimental results are presented to evaluate effects of the interlaminar properties on the strength and on the toughness of thick composite structural parts. Numerical analyses assess implicit and explicit finite element approaches to model the stress states in static load conditions and to predict the evolution of interlaminar damages.
