A modular approach to 3-D impact computation with frictional contact

An approach suitable for 3-D impact computation with a large number of unilateral friction contact surfaces is presented. Applications concern connection refined models for which the structure components are assumed to be elastic. It is a modular approach based on a mixed domain decomposition method and the LATIN method. The resolution process is iterative and operates over the entire time-space domain. Several examples are finally analyzed to show the methodʹs capability of describing shocks.
