摘要: 复合材料层板结构的优化设计方法,不仅考虑了面内问题的宏观特性,而且考虑了层间应力分布的不均匀性。用面内弹性模量和层间应力分别作为设计空间的约束函数和目标函数。用SUMT法非线性程序确定最佳铺层方向。给出了一些典型的复合材料层板的优化设计结果。

Abstract: Art optimization procedure for the design of composite laminate structures is offered, considering not only the in-plane macroscopic behaviour, but also the non-uniformity of interlamina stresses. The in- plane modulus and interlamina stress are used as the constraint function and the objective function respectively. The ply-orienttation is optimized with non-linear programming (SUMT method). Some typical results of optimum design of composite laminates are obtained.
