A simplified method for axisymetric structures assembly computations. application to contact and friction problems

摘要

This paper is aimed at presenting a modular method of calculation for axisymmetric structures, capable of rapidly analyzing complex situations involving structural assemblages, with the account taken of non linearities (contact, friction) andcorrectly representing technological reality (prestressing, of bolts, clearances).The proposed approach is a refinement combining two processes. The first process consists In breaking down the structure into sub-structures and connecting elements, thus giving greater independence to the various elements. The second one Is theutilisation of an iterative and entirely parallel calculation method. An application of the method is made in the study of the assembling of aerospace structures.
