This work deals with a numerical investigation which has been carried out to study the crash behaviour of an automotive substructure located in the rear part of a vehicle, using a new stochastic methodology, Stochastic Design Improvement (SDI). Fundamentally, an iter-ative Monte Carlo simulation procedure was executed, whose trials consisted of deterministic numerical analyses based on explicit fnite element methodologies. The SDI procedure has been applied to reduce of a given amount the maximum displace-ment of a rigid barrier impacting against the rear substructure of a vehicle in a particular crash test. The procedure allowed an e±cient solution to the considered problem and the fnal results were validated through experimental tests.
