Abstract

It is practically important to know the value of stress intensity factor of hole or notch with a crack. In this paper, the problems of the tension of a semi-infinite plate having a 60° V-shaped notch with a crack or an infinite plate having a double 60° V-shaped hole with two cracks are analyzed by body force method. Furthermore, the error due to the use of equivalent crack length, which is the sum of notch depth and crack length, is discussed. Finally, a simple method for calculating F1 of a semi-infinite plate having a 60° V-shaped notch with a crack of an arbitrary size is presented.
