Impulsive Loading of Fiber-Reinforced Structures

Abstract

The work described concerns the response of metallic composite beams and simple structures to rapid dynamic loading. It has been shown experimentally that the observed plastic response of clamped beam specimens to very sharp transverse blows could be adequately described by the idealised theory formulated by Spencer and his colleagues so long as the duration was sufficiently short for the plastic wave not to reach the clamp. The reflection process for real clamping conditions was found to very much more complex. The effects of blows of much longer durations on beams and portal arches are also described, as well as the effects of rate-of strain on the yield point of the matrix metal.
