TL;DR: In this paper, an analytical model is presented assuming that the specific response of foams in compression can be assimilated to an elastic-perfectly plastic behavior, and the displacements and stress calculated with this two parameters model are compared with results given by Winkler's theory and Finite Element Method.

TL;DR: In this paper, an experimental and numerical study of an oblique impact on the skin of the blade of a helicopter rotor is presented, which is equivalent in a first approach to an impact on a sandwich panel made up of a foam core and a thin woven composite skin.

TL;DR: In this paper, the influence of several parameters, including the draping sequence and the fiber/matrix interface on the fracture toughness of woven composite laminates is studied.

TL;DR: In this article, a 2D Digital Image Correlation (DIC) technique based on customized interpolation functions is presented for the measurement of spherical impactor positions, velocities and acceleration (translations and rotations) during medium velocity impact experiments performed with gas-gun devices.

TL;DR: In this paper, an F.E. semi-continuous explicit model has been developed to identify the mechanisms of damage to the skin for different orientations of the firing axis and to develop a representative model of the damage kinetics adapted to the modeling of the complete structure.
