| Abstract: | The geometric material parameters of laminated composite plates were usually of random due to the effect of various un-deterministic factors in engineering structure. To study the sensitivity analyses and statistical properties of the plates with random parameters was of significant importance for estimating reliability of the structural design. With the perturbation methods, the directions of laid fibre, material density and distance from the upper surface to middle surface on the composite plates were regarded as randiom variable and the responsive sensitivites as well as statistic properties of random parameters under the condition of deteminative burden were studied in this paper. |
