摘要：

The extension of an approach, suitable for bolting structures impact computation with a large number of unilateral friction contact surfaces, and with local plasticity of the bolts, is presented. It is a modular approach based on a mixed domain decomposition method and the LATIN method. This iterative resolution process operates or er the entire time-space domain. A 3-D Finite-Element code is presented and dedicated to Applications concerning connection refined models for which the structure components are assumed to be elastic. Several examples are analysed to show the method's capability of describing shocks throw real three dimensional assembly. Comparisons between classical dynamic code LS-Dyna3d are presented.
