Abstract The varying mesh technique avoiding redundant elements has been proved to be computation efficient in finite element crack closure analysis. Because the element model varies every cycle, the calculated information has to be mapped from the old to the new model. The results of this new technique are highly related to the mapped stress quality. In this study, the causes that the mapped stress quality can be improved solely by good remeshing arrangements are studied. A hybrid technique combining the new and conventional techniques is proposed. It is found that this hybrid technique may further improve the calculated results.
