Analysis of Functionally Graded Shells Subjected to Blast Loads; Final rept. 1 Mar-30 Nov 2007

摘要

The response of doubly curved functionally graded panels exposed to blast loads and a uniform through the wall thickness temperature field is investigated. Two scenarios, symmetric and antisymmetric about the midsurface, continuous distributions of the two constituent phases, ceramic and metal, are considered, in the sense that in one of them the composition varies gradually from ceramic-to-metal-to-ceramic, while in the other, from ceramic-to-metal. The implications of pressure pulses, volume fraction exponent, panel curvature, and the temperature change on the time-history of the transverse deflection are presented, and pertinent conclusions are drawn.
