Most of the numerical simulations of dry textile reinforcements forming are based on a macroscopic approach and continuous material models whose behavior is assumed to be elastic (linear or nonlinear). On the one hand, the experience shows that under

International audience; Important information can be obtained by simulating the deformation of composite reinforcements on a mesoscopic scale. The knowledge of the direction and density of the fibres in the deformed reinforcement affects the mechanic

Simulations of the draping is currently based on membrane and out-of-plane bending stiffnesses of the composite textile reinforcements. In this article, an additional stiffness of in-plane bending of fibers is introduced. This stiffness gives rise to

International audience; A stress resultant shell approach is proposed to simulate the draping of textile composite reinforcements with continuous fibers. This approach naturally makes it possible to take into account the specificity of the deformatio

International audience; The deformation of textile composite reinforcements is strongly conditioned by their fibrous composition. Standard plate and shell theories are based on kinematic assumptions that are not verified for textile reinforcements. A
