Abstract: An appraisal is made of linear elastic fracture mechanics (LEFM) as a method of fracture-safe assurance for carbon and low-alloy steels. The theoretical advantage of an exact flaw size-stress ...

Abstract: Transition temperature concepts for fracture-safe design have been based on the relatively narrow temperature range evidenced by the fracture mode transition from plane strain to plane stress. ...

Abstract: Public safety agencies in many large metroplitan cities need a mobile system which is capable of safely transporting “terrorist-type” bombs from a discovery point to a disposal area. In view ...

Abstract: An experimental investigation was conducted to characterize the benefits of warm prestress (WPS) in limiting crack extension in the wall of a nuclear vessel during a LOCA-ECCS. The present ...

Abstract: Fracture-safe operating criteria for commercial nuclear pressure vessels based on fracture analysis diagram procedures and Charpy-V energy trends are reappraised with respect to the effects of ...

Abstract: The large scatter emerging from KIc measurements for heavy walled pressure vessel steels is examined in view of new data for A533B. Extensive plastic flow data at −220 deg F and 80 deg F ...

Abstract: The fracture behavior of thick-walled nuclear vessels is considered for the case of a radiation-induced toughness gradient through the wall which characteristically results from neutron attenuation ...
