| Abstract: | The geometric material parameters of laminated composite plates were usually random due to the effect of various undeterministic factors in engineering structure.To determine the effect of the randomness on the dynamic response for the plates had a significant importance for estimating reliability of the structural design.Sensitivity formulas of response for antisymmetri-cally laminated composite plates were presented by using random perturbation and response statistic of the plates with random parameters to deterministic load are investigated. |
