Simulation of Ductile Fracture in Pipeline Steels Under Varying Constraint Conditions
… T-stress (or constraint) variations on crack tip opening angle (CTOA) of pipeline steels using modified boundary layer (MBL), and (2) to simulate ductile crack propagation in pipeline steels using drop weight tear test (DWTT) and comparing these FE simulations with experimental results. …

The Influence of Reinforcement Architecture on the Fracture Behavior of Selectively Reinforced Materials
… finite element code ABAQUS. A three-dimensional crack propagation procedure based on the crack tip opening angle (CTOA) was developed using Python. Eleven different reinforcement architectures consisting of rectangular and triangular cross-section reinforcements were evaluated. Reinforced …

Crack Path Bifurcation at a Tear Strap in a Pressurized Stiffened Cylindrical Shell
… The shell contained an initial, axial through-crack centered between the straps. The crack propagated slowly in the axial direction as the pressure increased above a certain value until a maximum pressure was attained, and then the crack propagated dynamically. The tear straps sufficiently …
