Rice’s J-Integral

Need to find a parameter that characterizes fracture under elastic-plastic and fully plastic conditions, similar to the K parameter in fully elastic fracture.

• Development of the J-Integral
• developed in 1968 by J.R. Rice
• it is a path-independent integral which characterizes fracture in non-linear elastic components.
• Non-linear elastic components behave plastically when they are loaded in one direction only.
