RISBrittle Fracture in Heavy Section Welded T-Joints: Correlation Between Stress Intensity at Fracture and Small-Specimen Toughness Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A fracture mechanics analysis has been made of brittle fractures encountered during a program of fatigue tests of welded plate T-joints. Fracture toughnesses are in reasonable agreement with ...
Strain Rate Effects on Fracture Toughness of Ship Plate Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Full thickness fracture toughness of conventional ship plate grades, including modern high-strength steels, was determined at loading rates representing quasi-static, intermediate, and impact conditions. ...
Heat-Affected Zone Toughness of a TMCP Steel Designed for Low-Temperature Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this investigation was to provide a detailed evaluation of the heat-affected zone (HAZ) toughness of a high-strength TMCP steel designed for low-temperature applications. The ...
Crack Arrest Toughness of a Heat-Affected Zone Containing Local Brittle Zones
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The awareness of the presence of local brittle zones (LBZs) in the heat-affected zone (HAZ) of welds has led to the requirements for minimum initiation (CTOD) toughness for the HAZ for critical ...
