Abstract
A J-integral based tearing modulus approach is utilized for investigating crack growth instability in an elastic-plastic strain hardening material. A center-cracked panel of finite dimensions with linear elastic-piecewise power law hardening material behavior is analyzed under displacement controlled loading. Plane stress as well as plane strain situations are considered. Numerical results are presented for a linear elastic-piecewise power law representation and are compared with an alternate Ramberg-Osgood material representation. Stability of crack growth for a range of crack length to width ratio, a/b, of the panel is discussed via the tearing modulus parameter, T.
