STRAIN-ENERGY RATES FOR A CLASS OF PERTURBATIONS OF BOUNDARY GEOMETRIES,

Abstract

An argument of Irwin is formalized and extended within the framework of linear elasticity for the change in strain energy associated with a class of perturbations of boundary geometry. Application of the argument to the calculation of the rate of change of the elastic strain energy for a family of edge notches in tensile sheet is then demonstrated. (Author)
