Conception d'un systeme de flexion pure en grands deplacements geometriques/Analyse statique de pieces composites

摘要

The mechanical characterization of composite materials subjected to large displacements and rotations and the analysis of this evolution during tire loading involve many experimental difficulties. The aim of this research is to present air original device which allows bending loads with large deformations. Their tire pure bending is preserved during loading. A description of the design steps is presented, a non-linear geometrically mechanical model, being based on works of Simo (SIM 85) is developed and applied to a multilayered composite part.
