✦ Synopsis

The Westergaard method of crack analysis, published almost thirty years ago, is shown to be invalid for a class of crack problems dealing with the infinite medium with cracks under applied loads at infinity~ The necessary modifications of the Westergaard method are derived from the complex potential formulation of Muskhelishvili. The examples of a single line crack in an infinite plate owing to biaxial tension and pure shear are discussed. * The results presented in this paper were obtained in the course of an investigation carried out under Contract Nonr-610(06) with the Office of Naval Research in Washington, D.C.
