An influence function method has been developed to analyze stress intensity factors, K, for cracks which are subjected to arbitrarily distributed surface stresses. The method has been applied to the analysis of a series of influence coefficients for flat plates with an embedded elliptical crack. It has been shown, based upon the data of the influence coefficients, how easily the K-values for an embedded elliptical crack in a flat plate can be evaluated against arbitrarily distributed surface stresses.
