| 摘 要： | 本文在Reissner型平板裂纹尖端应力应变场一般解~2,3]的基础上,采用应力杂交法构造高阶奇异元。由于采用了奇异元并解决了单元协调问题,使得Ⅱ型、Ⅲ型应力强度因子均获得较好的计算精度。本文计算了有限尺寸板复合型弯曲应力强度因子,并对Reissner型板若干力学特性进行了讨论分析。

| Abstract: | Based on general solution of stress strain fields at crack tip in Reis-sner's plate, a high order singular element is ' proposed by using hybrid stress method. In this paper the bending stress intensity factors for finite size Reissner's plate were calculated with good accuracy both for mode II and III. Some features for finite size Reissner's plate were discussed. |
