On the entropy of fatigue crack propagation
, 2020Entropy 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 ...

A novel multi-grid based reanalysis approach for efficient prediction of fatigue crack propagation
Computer Methods in Applied Mechanics and Engineering, 2019In order to model the fatigue crack propagation of engineering structures with high efficiency, a novel multi-grid (MG) reanalysis method is formulated in this study under the framework of the extended finite element method (XFEM).
