Line 37: CTOD is a single parameter that accommodates cracktip plasticity. It is easy to measure when compared with techniques such as J integral. It is a fracture parameter that has more physical meaning than the rest. However, the ~~equavalance~~equivalence of CTOD and J integral is proven only for non-linear materials, but not for plastic materials. It is hard to expand the concept of CTOD for large deformations. It is easier to calculate J-integral in case of a design process using [[finite element method]] techniques. == References ==
