Abstract: By applying a slip-line fields solution for general yielding, which includes the tup indenter for Charpy V-notch and precracked Charpy tests, estimates of high loading-rate yield stress values ...

Abstract: This paper presents a comparison of dynamic fracture initiation results obtained from two independent experimental methods: (1) the instrumented version of the precracked Charpy test and (2) a ...

Abstract: Recently developed statistically-based fracture toughness reference curve procedures (Charpy V-notch and precracked Charpy methods) have been applied to unirradiated and irradiated plate and weld ...

Abstract: The problem of obtaining a meaningful value of toughness from small Charpy-size surveillance specimens, tested at temperature corresponding to the upper shelf where ductile fracture predominates, ...

Abstract: The mechanistic models of radiation embrittlement for reactor vessel steels are reviewed and direction for improving these models is provided. Improvement in these mechanistic models will lead ...

Abstract: A methodology is presented upon which an effective material property design curve can be based. The methodology is a statistically developed procedure which allows appropriate confidence limits ...

Abstract: For much of the high-energy piping in light water reactor systems, fracture mechanics calculations can be used to assure pipe failure resistance, thus allowing the elimination of excessive rupture ...
