Abstract: This paper presents a critical comparison of the traditional strength criteria and the modern plastic flow criteria used in the structural design and integrity assessment of pressure vessels. This includes (1) a brief ...

Abstract: The Jintegral resistance curve (or JR curve) is an important fracture property of materials and has gained broad applications in assessing the fracture behavior of structural components. Because the Jintegral concept was ...

Abstract: Pressure vessels (PVs) are widely used in the energy industry. Accurate burst pressure is critical to structural design and safe operation for both thin and thick-walled PVs. The traditional strength theories utilized a ...
