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
