On the entropy of fatigue crack propagation

B. Hajshirmohammadi, M.M. Khonsari

Abstract

Abstract Entropy flow from the plastic zone ahead of a crack tip is predicted analytically and measured experimentally for stainless steel SS304. It is shown that crack propagation rate is related to the entropy flow during cyclic loading of a flat specimen in mode I. The results show that entropy flow is a reliable parameter for the prediction of crack propagation rate in both low- and high-speed regions. It is also shown that the application of the degradation entropy generation theorem provides a method for evaluating the constant in Paris law in terms of entropy flow.
