Abstract
This paper investigates the elastoplastic behavior of a two-dimensional solid with rectilinear cracks. Plastic strip model is used to reduce plasticity problem to the equivalent linear eleasticity formulation. The effective mechanical response predictions are obtained for mode I and mixed-mode cracks. For mixed-mode cracks, the modification of Dugdale (1960) model proposed by Becker and Gross (1988) is applied. Results are compared with known elastic solutions.
