Study of structural assemblies in the presence of uncertainties
Résumé
The objective of the work presented is to develop a suitable strategy for the sensitivity analysis of assemblies including contact with friction, gaps, elastically bonded joints… The approach consists in developing an application of the LArge Time INcrement (LATIN) method for the parametric analysis of static problems with multiple joints. Our approach is based on a decomposition of the assembly into substructures and interfaces. The interfaces play the vital role of enabling local nonlinearities, such as contact and friction, to be modeled easily and accurately. The problem is solved in each substructure by the finite element method, and an iterative scheme based on the LATIN method is used for the global resolution.
