摘　　要：通过对两对边简支两对边自由矩形板在简支边有均匀压力作用下的稳定问题的研究，得出了板的失稳波形与临界荷载的二阶渐延表达式。In this paper, we have studied the buckling of rectangle plates with the boundary conditions of two opposite edges being simply supported and acted by homogeneous pressure, and the others being free. Two order approximate solutions of buckling wave form and critical loads are obtained, and numerical results of the critical loads for five kinds of meterials are also given.

关 键 词：矩形板 失稳 临界载荷
