Response of a Fiber Composite Laminate to a Time-Varying Surface Line Load

Abstract

A symmetric cross-ply laminated plate consisting of four layers of a fiber-reinforced composite material is subjected to a time varying line load on its upper surface. The response at points remote from the application of the line load on both upper and lower surfaces of the plate is determined. Two different pulses are considered, namely a square pulse and a half-sine pulse. The significant parameter governing the nature of the response is the duration of the pulse.
