Abstract
The solution of linear elastostatic problems in the neighborhood of singular points is characterized, by a sequence of eigenpairs and their coefficients, called generalized stress intensity factors (GSIFs). For general singular points, as cracks in anisotropic multimaterial interfaces, and V-notches in composite materials, only numerical approximations of the eigenfunctions are available. This note addresses the question: how should the GSIFs computed using the numerically determined eigenfunctions be interpreted?
