DEVELOPMENT OF THE PROGRAM SPECEL: A SPECIAL ELEMENT FOR ELASTO-PLASTIC CRACK TIP ANALYSIS

Theory is stated in terms of increments of displacement and stress, and of instantaneous or accumulated values of stress. The equilibrium equations, in the absence of body forces, are written, along with constitutive relations for plane strain. (Author)
