简支矩形复合材料层板的最大轴压临界载荷分析
AN ANALYSIS OF MAXIMUM UNIAXIAL CRITICAL LOADS FOR SIMPLY SUPPORTED RECTANGULAR LAMINATES
-
摘要: 本文分析并解释了多叠层简支矩形层合板的单轴压临界载荷随板的铺层状态而变化的现象。从而指出了提高临界载荷的最佳铺层方式。本文例题给出的最大临界载荷所对应的铺层角,与文献[3]优化设计的结果一致。Abstract: The deyendenne of the uniaxial critical load for simply supported rectangular nmlti-ply laminated platos ou the state of their laminated layers is analyzed and explained.To increase the critical load of the plate the best form of lamination is indicated.Lamination angles corresponding to the maximum critical loads given in the calculated examples of this paper agree well with what is in Ref.[3]where the optimality criteria is used.
