Pressure dependent yield criteria applied for improving design practices and integrity assessments against yielding of engineering polymers

Conventional yield criteria for ductile materials, such as Tresca and von Mises, predict that yielding is independent on the hydrostatic stress state (pressure), which means that tensile and compressive stress-strain behaviors are considered equal and are equally treated. This approach is reasonable...
