| 摘 要： | 本文将复变应力函数的迭加解法进一步推广应用于求解一般的多孔边裂纹问题.文中阐明了这种复变应力函数迭加解法的基本原理,并用此方法计算了双孔、三孔和四孔边裂纹板的若干数值例子.考核计算表明,对于双孔平行边裂纹板(M=4),其应力强度因子解K_1与文的解相对误差小于7%.因而,用本文方法解已能满足一般工程精度要求.

| Abstract: | In the present paper, the superposition method of the complex stress function is extended to calculate the general problems concerning radial cracks emanated from the multiple circular holes. The basic principles of the method are described, and some numerical examples of the radial cracks appearing at the boundary of twin, three and four circular holes are calculated. The results of the examined examples indicate that the numerical solution ? of an infinite plate containing parallel radial cracks emanated from the twin-holes given in the present work is 7% less than those given in (2).Therefore, it is clear that the accuracy of solution as described in the present paper is satisfactory for engineering application. |
