复合材料层合板的热屈曲荷载的优化设计

对均布温度荷载作用下，复合材料层合板的热屈曲荷载最优化设计采用的改进可行方向法进行研究。目标函数可使层合板临界温度最大化，将纤维方向设为设计变量，数学公式中采用了一阶剪切变形理论。为此，采用一个基于FORTRAN的计算机程序来进行层合板的优化。最后，分析了长宽比、反对称铺层、边界条件、材料各向异性、热膨胀比例系数和复合层合板对研究结果的影响，并将结果进行对比。

Thermal Buckling Load Optimization of Laminated Composite Plates

In this study, the applicability of the Modified Feasible Direction (MFD) method on the thermal buckling optimization of laminated plates subjected to uniformly distributed temperature load is investigated. The objective function is to maximize the critical temperature capacity of laminated plates and the fiber orientation is considered as design variable. The first-order shear deformation theory is used in the mathematical formulation. For this purpose, a program based on FORTRAN is used for the optimizati...
