RISThe Sensitivity to the Lode Parameter in Ductile Failure of Tubular Steel Grades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ductile failure in steels is highly controlled by the stress state, characterized by the stress triaxiality (T) and the Lode parameter (L). The ASME Boiler and Pressure Vessel Code requires pressure vessels to be designed ...
New Ring Specimen Geometries for Determining the Failure Locus of Tubulars
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure vessels designed in accordance with the ASME BPVC code are protected against local ductile failure. Recent work has shown that local ductile failure highly depends on the stress state characterized by both stress ...
