Two-Parameter Model of a Mode I Crack in an Elastoplastic Body under Plane-Strain conditions

  • Published:
International Applied Mechanics Aims and scope

Abstract

The Dugdale crack model is generalized to the case of plane strain. The governing equations are set up to determine the stresses in the plastic zone. Numerical results from specific problems are analyzed and compared with those for plane stress state and other cases. A relationship between the crack model and K I-T theory is established in the case of small-scale yielding at the crack tip
