Abstract

This paper presents a comprehensive investigation on optimum layer thickness and fiber orientations of laminated composite plates against buckling under complex loading conditions by using a new optimization procedure that effectively utilizes computational efforts. In this proposed procedure, a finite element model of the laminated composite plates is developed for the buckling analysis and the interior point optimization procedure is used to maximize the buckling coefficient, aiming to determine the optimum values of fiber orientation angles and thickness. In optimization scenarios, the laminated composite plates are subjected to single and complex loading conditions, including compression, shear, bending and a combination of two or more of these loading types. The computational performance of the proposed optimization procedure is evaluated to investigate and present the effect of various factors including the number of layers, length-to-thickness ratios, aspect ratios, and boundary conditions on the optimum buckling analysis.

层压复合板在不同加载条件下抗屈曲破坏的最佳层厚和纤维取向综合研究

本文采用一种新的优化程序，有效利用计算能力，对层压复合板在复杂载荷条件下抗屈曲的最佳层厚和纤维取向进行了全面研究。在该程序中，为进行屈曲分析建立了层压复合材料板的有限元模型，并使用内点优化程序使屈曲系数最大化，从而确定纤维取向角和厚度的最佳值。在优化方案中，层压复合板承受单一和复杂的加载条件，包括压缩、剪切、弯曲以及两种或两种以上加载类型的组合。对所提出的优化程序的计算性能进行了评估，研究并展示了层数、长厚比、纵横比和边界条件等各种因素对最佳屈曲分析的影响。
