中心裂纹板张开位移研究

Engineering Solution and Finite Element Solution of Crack Tip Opening Displacement for Surface Plate with Center Through Crack

首先对ＥＰＲＩ方法建立的裂纹中心板张开位移的工程解进行了实例计算，然后用有限元法对平板中心穿透裂纹张开位移计算得到的有限元解与其进行了比较。

Engineering solution of crack tip opening displacement for surface plate subjected to uniformly distributed forces with center through crack is derived.Crack tip opening displacement for surface plate subjected to uniformly distributed forces with center through crack is calculated by using finite element method.Results by finite element method are compared with results by engineering method.A conclusion that the engineering method is more conservative is reached.
