Paper Title
The Digital Investigation on the Behavior of a Composite Material’s Structure is Requested by an Effort Type '' Shock ''

Abstract
numerous studies are already made in the field of fast dynamic, which is expressed in our case by solicitation of impact that is still relevant. Various difficulties associated with the solicitation of shock are just added to us in studying the problems of composite materials, including their homogenization or characterization. For this purpose, our present investigation is concerned with the study of the influence of the impact plates in the composite material. For this, calculation software was used and the chosen structure is sandwich plates. The Characterization tests were performed have then allowed to complete the data required for various applications made. The obtained results are Index Terms - Shock, Sandwich Plate, distortion
