| 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. |
