【Abstract】 The geometric material parameters of laminated composite plates are usually random due tothe effect of various undeterministic factors in engineering structure. To determine the effect of therandomness on the dynamic response for the plates has a significant importance for estimating reliability ofthe structural design. Sensitivity formulas of response for antisymmetrically laminated composite plates arepresented by using random perturbation and response statistics of the plates with random parameters todeterministic load are investigated in this paper.更多还原
