Research on Fatigue Crack Propagation of 304 Austenitic Stainless Steel Based on XFEM and CZM
Metals, 2020 The fatigue crack propagation of 304 austenitic stainless steel was studied both by experiments and numerical simulations. Two methods were applied to simulate the crack propagation: the extended finite element method (XFEM) and the cohesive zone model ...

Buoyancy-driven crack propagation from an over-pressured source [PDF]
, 2005 The propagation of a liquid-filled crack from an over-pressured source into a semi-infinite uniform elastic solid is studied. The fluid is lighter than the solid and propagates due to its buoyancy and to the source over-pressure.

Crack growth behaviour of aluminium wrought alloys in the Very High Cycle Fatigue regime [PDF]
MATEC Web of Conferences, 2018 Investigations have shown that in the regime of Very High Cycle Fatigue (VHCF) “natural” crack initiation often takes place underneath the material surface leading to crack propagation without contact to atmospheric components.

A Time-Integral Crack Propagation Model Considering Thickness Effect
IEEE Access, 2019 The crack propagation mechanism of thick plates is difficult to describe accurately, and thus, it is difficult to predict the lifetimes of thick plate structural cracks in extreme construction environments.
