【摘要】 讨论了双向增强层合板在面内载荷作用下使屈曲载荷最大的铺层优化分析，从数 学上证明了在压缩及剪切载荷同时作用下使屈曲载荷最大的最优铺设结构必定是对称 铺设结构，并且无论其层数是多少其最优铺设角不会超过３个不同角度。同时，讨论 了材料刚度比变化对最优铺设角的影响。更多还原

【Abstract】 The optimum analysis of bidirection reinforced laminated plates under in-plane load is discussed. It is proved that for the largest buckling load of plate under combined axial compression and shear load the optimum laminate configuration laminated plate must be symmetrical and the number of different ply angles in an optimum laminated plate is no more than 3. The effect of ratio of stiffness of material on optimum ply angles is also discussed.更多还原
