Researchers have developed a simplified mathematical model (step-loading model, SLM) that unifies two earlier mechanisms to describe the velocity jump in crack propagation. Through SLM, they ...

The virtual crack closure technique (VCCT) is implemented to model the propagation of the fracture process zone (FPZ). This model can be calculated the energy release rate by using new method from ...

After that, a grain distribution model of the drill pipe material at the mesoscale was established by the Python scripting language on ABAQUS platform. Furthermore, the extended finite element method ...

It furthermore introduces new concepts for the numerical treatment of fatigue microcrack propagation and their implementation in fatigue-life prediction models.This comprehensive overview of the whole ...

These films exhibit remarkable mechanical properties, including excellent crack-propagation resistance without any additives, and are easily recyclable, paving the way for more environmentally ...
