Application of the Strain-Energy-Density Theory to Fundamental Fracture Problems.

Abstract

This study describes some essential features of the fracture problem associated with the analytical modeling of a crack. Topics chosen for investigation are: (1) slanted crack, (2) crack tip notch effect, (3) MATERIAL NONHOMOGENEITY, AND (4) fracture in three dimensions. A brief discussion is also given to crack propagation in the presence of plastic deformation. All the analyses are based on the strain-energy-density factor, S, concept which assumes fracture to occur in an element ahead of the crack when S REACHES ITS CRITICAL VALUE, Sc. (Author-PL)
