摘要: 本文导出了考虑剪切变形影响的圆板在轴对称情况下的大挠度方程。利用它对弯曲问题进行分析,并求得了圆板的压屈临界载荷。这些结果比经典理论解更为精确。Abstract: Starting from Reissner's theory with particular attention to the shearing effect, amore precise equation for large deflection was derived, and by which the shearing defor-mation involved in the symmetrical circular plates was investigated analytically. By thisequation, the bending problem and buckling load of a circular plate were discussed. Abetter approximation than those from the elassical theory is obtained.
