Effect of welding residual stress on load-carrying capacity of girth-welded pipelines with cracks

Hanjie xuebao
To address the unclear effects of welding residual stress on the load-carrying capacity of girth-welded pipelines with cracks, a dynamic fracture finite element model was established to investigate the bearing capacity of girth-welded pipelines with ...

Proposal of determination method for the material parameters of the GTN model based on sensitivity analysis by the Monte Carlo method

Nihon Kikai Gakkai ronbunshu
Fracture analysis using damage mechanics models such as the GTN (Gurson-Tvergaard-Needleman) model is applied for the purpose of limit load or limit strain evaluation of structures.

Study on Fracture Behavior of Mini-CT Specimen Based on GTN Mesoscopic Damage Model

Yuanzineng kexue jishu
To ensure the safe operation of nuclear power plants, the status of the reaction pressure vessel needs to be monitored in real time. The fracture toughness of the domestic A508-Ⅲ steel, which is the main material, can be used as the primary indicator to ...

Phenomenological–based strategy for the Gurson-Tvergaard-Needleman model parameters identification

The Gurson–Tvergaard–Needleman GTN model is widely used for ductile fracture simulations. However, the selection of its parameters is often done randomly to reproduce the experimental data without considering the physical consistency of the set of ...
