Résumé

Abstract : The composite materials are of very important interest in the field of the modern industrialists applications such as: mechanics, aeronautics, civil engineering and biomechanics considering their hardness their lightness and their super elasticity. During their operation and under the effect of the external efforts, these materials can undergo crackings or ruptures which can cause the disaster of the structure. During their operation and under the effect of the external efforts, these materials can undergo crackings or ruptures which can cause the disaster of the structure. In order to avoid these types of problems, the analysis of these materials is necessary in order to predict their mechanical characteristics and thus to prolonging the life of structure. This analysis is contingent primarily on the internal structure of material, its geometry, its boundary conditions and the external conditions applied. On the basis of numerical modeling, the code Abaqus was used to simulate the behavior with the impact to envisage the behavior of the structures in composite requested with the impact. This work consider the influence of the inclination and the position of the impactor on a plate in material composite graphite/epoxy of laminated [03/904/03] under loading by dynamic impacts to study the evolution of the force impact, the displacement and the internal energy of deformation.
