WebThe source of the difficulty is traced to an oversight in an earlier work by MacGregor, upon whose work Westergaard based his equations. Several examples of interest illustrating the consequences of the necessary correction to these equations are given. WebJan 1, 1979 · Early on, Irwin [4] modified the Westergaard equations to include an arbitrary uniform stress in the direction parallel to the crack. An analytical review of this …

WebIn 1939, Harold M. Westergaard developed a solution for the stress field surrounding a crack that has two advantages over Inglis's solution [2]. First, Westergaard's solution applies directly to cracks, not to an ellipse that approaches a crack in the limit. Second, the solution is expressed in rectangular coordinates rather than elliptical coordinates. WebThe original equations developed by Westergaard (1926 [2]) for three critical load locations will be presented. The critical load locations are (after Bradbury, 1938 [1] and … rebaja luz gobierno
