Numerical simulation for studying constraint effect on ductile fracture initiation using complete Gurson model [PDF]
FME Transactions, 2010 Ductile fracture initiation in high-strength low alloyed welded steel joints is predicted using micromechanical complete Gurson model (CGM). The crack tip constraint and variation of stress triaxiality in ligament are considered on single-edge notch bend

A novel method for imitating true-triaxial stress path with conventional triaxial apparatus
Geomechanics and Geophysics for Geo-Energy and Geo-ResourcesAbstractThe stress paths of the cylindrical specimen in the p–q stress space by controlling the ratio of the axial and the radial loading is guaranteed to be consistent with the cuboid specimen, a novel method for imitating true-triaxial stress path by conventional triaxial apparatus was presented.
