A local stress approach for ductile crack propagation (Integration into the GTN model framework and demonstrations)

Mechanical Engineering Journal
A local stress approach, employing failure conditions derived from notched round-bar tensile tests has successfully traced the ductile crack propagation in compact tension (CT) specimens. The failure condition is expressed using the failure stress index (

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 ...
