摘要
本文提出了用权函数法来推导承受轴对称载荷无限大体圆盘裂纹D-M模型之裂纹张开位移COD一般公式.应用它计算了四种载荷情况的COD,可供工程上应用.本文的方法具有计算简便的优点,
This paper is the continued work of reference[l].According to the D-M model, the common formula of a crack tip opening displacement COD for a penny-shaped crack stretched to an axial symmetrical load in an infinite solid is derived by using the weight function method.The formulae of COD for four loading cases are obtained by using one.The presented method is very simple.The given results are very useful in engineeriug.
