International Conference and Exposition on Structural Impact and Crashworthiness at Imperial College, London, 16-20 July 1984

摘要

This report summarises the main keynote papers and conference papers for the International Conference on Structural Impact and Crashworthiness, held at Imperial College of Science & Technology, London, U.K. attendees had different interests in high and low velocity impact, low velocity crashworthiness of aircraft, trains, ships and helicopters, and high speed ballistic perforation. Most of the papers concerned metal impact in which plasticity and gross deformations control the energy absorbing process. There was one day devoted to composites (mostly glass and carbon/graphite) where energy absorption is quite different. Several full-scale tests were reported and filmed, including two U.K. crash tests reported for the first time in public: a nuclear fuel cell impacted at 100 m.p.h. by a complete train, and a drop test with a lynx Helicopter. The Pending Boeing 720 crash test was reviewed. The growing reliability of numerical programs for predicting crash response was evident, but there is still a long way to before computational programs become a design tool. It was clear that both in Europe and the U.S.A. the reliable use of finite element/finite difference codes for simulating crash cases is an urgent need, with an experimental validation used once only.
