Simplified estimates of the creep crack growth parameter C(t) under primary/secondary stresses using the enhanced reference stress method

This paper describes simplified methods to estimate the fracture mechanics parameter, C(t), related to creep crack growth rates in non-steady state creep conditions produced by primary or secondary stresses. The methods proposed incorporate effects from initial plasticity and redistribution during a...
