An efficient computational strategy for composite laminates assemblies including variability

The aim of this work is to present an efficient numerical strategy for studying the influence of the material parameters on problems involving 3D assemblies of composite parts with contact and friction. This approach is based on the multiscale LATIN method with domain decomposition and its ability to reuse the solution of one problem (for a particular set of parameters) to solve many similar problems, each associated with another set of parameters. The presentation of the proposed calculation method will be followed by two sample applications, one with variabilities in the cohesive interface laws and the other with variabilities in the damageable behavior laws, which characterize the composite material.
