摘要
研究了弹性体为整个平面,且至少含有两个基本循环对称区域,在每一个基本循环区域中只含一条直裂纹的第一基本问题,给出裂纹尖端附近应力的极限状态和应力强度因子.结果表明,在循环对称条件下,各基本循环区域中相对应的裂纹尖端附近应力的极限状态和应力强度因子是相同的.
The first fundamental problem of every basic cycle symmetrical area with only one straight crack on the infinite elastic plane which at least contain two basic cycle symmetrical areas is considered.The limits of the stress and the stress intensity factors at the crack tips are also derived.It is found that the limits of the stress at the crack tips correspondingly in every basic cycle symmetrical area are the same,and the stress intensity factors are also identical.
