Mode Mixity Parameters for Mathematical Crack Type

Abstract: 

A method for calculating the elastic-plastic stress intensity factors for full range of mixed mode loading from tensile to shear crack is suggested. The state of arbitrary oriented straight-line crack in form of mathematical notch under biaxial loading is considered. The solution is based on a combination of both the compatibility strain equation and the Airy stress function with its derivatives. The elastic-plastic material behavior is represented by the Ramberg – Osgood model. On the base of obtaining results the influence of both mode mixity and material plastic properties,describing by strain hardening exponent,ontheelastic-plasticstressintensityfactors is stated.
