Fatigue crack paths in coarse‐grained magnesium
Fatigue & Fracture of Engineering Materials & Structures, 2004 ABSTRACTThis paper examines fatigue crack paths in coarse‐grained magnesium alloys. Visualization of the microstructure by etching and continuous crack monitoring with a microscope provide evidence of the crack‐grain interaction at different fatigue crack growth regimes.

The effect of creep damage model formulation on crack path prediction
Fracture and Structural Integrity, 2019 The stress, strain rate and process zone with respect to the creep-crack growth are analyzed by employing damage-evolution equations. The damage models for the fracture of the process zone are represented using a stress and ductility based formulation ...

Crack paths and the linear elastic analysis of cracked bodies
Frattura ed Integrità Strutturale, 2015 The linear elastic analysis of cracked bodies is a Twentieth Century development, with the first papers appearing in 1907, but it was not until the introduction of the stress intensity factor concept in 1957 that widespread application to practical engineering problems became possible.

Path Independent Integral to Creep Crack and Crack Energy Density
Bulletin of JSME, 1984 The crack energy density e and eJ-integral which is the path independent expression of e are applied to creep problem and it is shown that e and its differential coefficient with respect to time e^.st are valid parameters to creep crack without any restriction on constitutive equation. The contents of the paper are as follows.
