Determination of constraint limits for cleavage initiated toughness data
Abstract The proper constraint limits for cleavage initiated toughness data within the ductile-to-brittle transition regime have been studied extensively using both numerical analysis and analysis ofExpand
Development of Consistent Size Criteria for ASTM Combined Fracture Mechanics Standards
Recent ASTM Subcommittee E08.08 on Elastic-Plastic Fracture Technology activities have concentrated on the development of a common fracture test standard that allows the evaluation of elastic andExpand
An Evaluation of the Neuber and Glinka Relations for Monotonic Loading
This paper evaluates the abilities of six models of notch root behavior by comparing them with experimental results over a range of constraints. The models are: The Neuber model, the Neuber model asExpand
Weibull stress model for cleavage fracture under high‐rate loading
This paper examines the effects of loading rate on the Weibull stress model for prediction of cleavage fracture in a low-strength, A515-70 pressure vessel steel. Interest focuses on low-to-moderateExpand
Investigation of Specimen Geometry Effects and Material Inhomogeneity Effects in A533B Steel
The Master Curve method and the associated reference temperature, asdefined in the new test standard ASTM E1921, is rapidly moving from the researchlaboratory to applications in the U.S. commercialExpand
Experimental Investigation of Mismatched Weld Joint Performance
A mismatched welded component exists when the strength of the weld material is different than the strength of the base material. This research examined the effect of weld joint geometry and theExpand
LOCA frequency evaluation using expert elicitation
The double-ended-guillotine break (DEGB) criterion of the largest primary piping system in the plant, which generally provides the limiting condition for the emergency core cooling systemExpand
Feasibility Study of Alternating Current Potential Drop Techniques for Elastic-Plastic Fracture Toughness Testing
A prototype alternating-current potential drop (ACPD) measurement technique has been developed for quasistatic and dynamic J-R curve testing. This well-known technique has classically been used inExpand
A Novel System for Miniature and Micro Specimen Fatigue and Fracture Testing.
Abstract : A microspecimen testing system has been developed to conduct real-time fatigue and fracture measurement on specimens less than 1 mm thick. Principal components include anExpand
SEM stereo-section fractography observations. Final report
Cleavage initiation in engineering materials is governed by local microstructural inhomogeneities. These features are often the principal reason for the large scatter evident in fracture toughnessExpand
