Crash Simulation snd Verification for Metallic, Sandwich and Laminate Structures,

Abstract

This paper outlines some of the research for crash simulation of structures using metallic and composite construction recently undertaken at ESI. Several current areas of interest are reviewed including helicopter stiffened panel construction, automotive structures and, on a micro level, the compressive failure analysis of Carbon-Epoxy test coupons. In each study a specialized Finite Element code is used. The dynamic buckling behaviour of panels stiffened with 'Z' sections are simulated numerically. The various components are connected using specially developed 'rivet' elements that fail at a prescribed load and are intended to produce a controlled collapse mode. These panels form the lower structure of a helicopter frame which also houses a flexible membrane fuel compartment. (JES)
