| Abstract: | The geometric parameters of composite material laminated plates are usually random due to the effect of various undeterministie factors in engineering structure. The study of the sensitivity of random parameter laminated plates and the analysis of its optimum design. Of parameter play an important role in the right estimation of the reliability of construction design. This article leads to the calculation formula of responding sensitivity of antisymmetrically laminated plates and studies the responding sensitivity and optimum design of random paramter of antisymmetrically laminated plates, by using random perturbation law. It uses the mesk law to calculate the best angle of araning lamination. |
