Controlling structural failure modes during an impact in the presence of uncertainties

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

A methodology to enforce a given structural dynamic behavior during an impact is presented. The approach identifies distinct structural dynamic behaviors using designs of experiments and data mining techniques. The changes of behavior are studied with respect to variations of deterministic design variables and uncertainties. Based on the probabilistic distributions of random parameters, failure regions of unwanted behaviors can be identified. A measure of the likelihood of occurrence of unwanted deformation modes is defined and is minimized with respect to design variables. The methodology is specialized to the location of structural fuses on a tube impacting a rigid wall. The locations of fuses are found so that crushing of the tube is enforced while taking uncertainty on the wall thickness into account.
