The internal structure of composite materials is modified during manufacturing. The formation of woven prepregs or dry preforms changes the angle between the warp and weft yarns. The damage behaviour of the consolidated composite is modified by these

The failure of laminated composite structures is linked to the numerous mechanisms that can appear during the material degradation phase under loading. The approach proposed here is to use Continuum Damage Mechanics to describe the matrix degradation

International audience; This study addresses the application of the modified Constitutive Relation Error to field identification problems in the framework of elastostatics. We show how relevant is the addition of a gradient-penalizing regularization

A dumbbell-shaped tube is designed in order to study the compression of composites in the direction of the fibers. Three conditions are defined that ensure the validity of the experimental procedure: the cracks appear in the middle of the specimen, t

International audience; The damping in a carbon fiber reinforced plastic (CFRP) laminate is greater than that which occurs in most metallic materials. In the supercritical regime, the damping can trigger unstable whirl oscillations, which can have ca

A non local ply scale criterion was previously developed for predicting the failure of balanced woven ply structures with stress concentrations. This non local criterion was based on the mean values determined over a Fracture Characteristic Volume (F

A ply scale continuum damage model for predicting the mechanical behaviour of an unbalanced woven fabric composite up to first failure is presented. The behaviour of the unbalanced woven plies and the evolution of the damage were investigated experim
