The stress states and the asymptotic solution of bending SIF for cracked plates including transverse shear deformation are investigated by the asymptotic approach.The whole cracked plate governed by Reissner plate theory can be divided into three differentregions by their stress characteristics,that is,the interior region(region Ⅰ),the Reis-sner boundary layer(region Ⅱ),and the singular region around the crack tip(regionⅢ).Eigen-expansion analysis is used to get the stress-displacement field around thecrack...

The stress states and the asymptotic solution of bending SIF for cracked plates including transverse shear deformation are investigated by the asymptotic approach.The whole cracked plate governed by Reissner plate theory can be divided into three differentregions by their stress characteristics,that is,the interior region(region Ⅰ),the Reis-sner boundary layer(region Ⅱ),and the singular region around the crack tip(regionⅢ).Eigen-expansion analysis is used to get the stress-displacement field around thecrack tip,and two different matching schemes are provided to find the bending SIF.Forthe case of symmetric loading,the zero order approximation of stresses and displace-ments,as well as a general integral expression for bending SIF,are found by the region-to-region matching scheme.When the small parameter (?) tends to zero,the simple relationsbetween the bending SIF for Reissner's plate theory and that for Kirehhoff's plate theoryare also established as follows:K_1~R=((1+v)/(3+v))K_1~C K_2~R=K_2~CBaed on the above results,the stress state characteristics of cracked plates and the method for simplifying the calculation are discussed.

本文用文[1]的渐近分析方法,研究了考虑横向剪切变形的含裂纹平板的应力状态和应力强度因子的渐近解.在Reissner 平板理论的范围内,将含裂纹平板的应力状态分解为外场区(Ⅰ区)、Reissner 边界效应区(Ⅱ区)和裂纹尖端附近的奇异性区(Ⅲ区)等基本应力状态.用特征分析方法,导出了裂纹尖端区的应力——位移场;并提出了两种匹配展开的渐近求解方案:对载荷对称情况,用逐区匹配求解的方法求得了当小参数趋近于零时,含裂纹平板的应力场与位移场的渐近解和应力强度因子的一般积分表达式;并证明当小参数趋近于零时,对应于对称型(Ⅰ型)、反对称型(Ⅱ型)的应力强度因子K_1~R、K_2~R 和按古典平板理论提法下的应力强度因子K_1~c、K_2~c 之间存在简单的解析关系:K_1~R=((1+v)/(3+v))K_1~c,K_2~R=K_2~c在此基础上,讨论了含裂纹平板应力状态的特征和简化计算的方法.

Reissner's plate theory by which the effect of transverse shear deformation on bending plates has been taken into account in particular.

In this paper, the Conception of generalized simply supported edge is complemented and extended. In accordance with E. Reissner's plate theory, the exact solution is obtained for the bending of the cantilever rectangular plate under uniformly distributed load by using the method of superposition. Since the effect of transverse shear deformation on bending of plates has been taken into account, the results can also be applied to moderately thick plates.
