Anisotropic Gurson‐Tvergaard‐Needleman plasticity and damage model for finite element analysis of elastic‐plastic problems

International Journal for Numerical Methods in Engineering, 2018
Implementation and analysis of the anisotropic version of the Gurson‐Tvergaard‐Needleman (GTN) isotropic damage criterion are performed on the basis of Hill's quadratic anisotropic yield theory with the definition of an effective anisotropic coefficient ...

Simulation of fracture of a tubular X-joint using a shear-modified Gurson–Tvergaard–Needleman model

Thin-walled structures, 2018
The full-range behaviour of materials and connections is important in the research of progressive collapse resisting mechanisms and structural seismic behaviour. There have been several recent studies on the fracture simulation of tubular joints. However,
