摘要
本文采用配方法,导出了采用应变能密度因子理论求解复合型裂纹脆性断裂角的精确公式。该公武为四次方程,可用公式法求出精确解,为处理全复合型裂纹的扩展问题,得到了精确、简便的计算方法。
In this paper, the formula of a exact solution for the fracture angle of the fragile fracture of compound crack is got by use of the fitting square method, which is determined by the theory of strain energy density factor. This formula is a four-order equation. It's exact solution is determined by the formula method. A exact, simple and convenient calculation method is obtained for solving the problem of full compound crack.
