RISFracture Safety Analysis Concepts for Nuclear Pressure Vessels, Considering the Effects of Irradiation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the most important aspects of the growth of nuclear power has been the development and use of quantitative methods of analysis for insuring the reliability of plant components and for ...
Effects of Crack Size on the Gross-Strain Crack Tolerance of A-533-B Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gross-strain crack tolerance is a measure of fracture toughness that is useful where yielding precedes fracture yet flaw size must be treated quantitatively. In these tests, rectangular bars ...
A J Integral Analysis for the Compact Specimen, Considering Axial Force as Well as Bending Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An important fracture mechanics problem is the determination of fracture toughness values with small specimens that fail after yielding. The J integral has an explicit meaning in terms of notch ...
Applications of Energy Release Rate Techniques to Part-Through Cracks in Experimental Pressure Vessels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In nonlinear applications of computational fracture mechanics, energy release rate techniques are used increasingly for computing stress intensity parameters of crack configurations. Recently, deLorenzi ...
Test of Thick Vessel with a Flaw in Residual Stress Field
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A 152-mm-thick cylindrical test vessel fabricated of A533, grade B, class 1 steel, was pressurized to failure at −23°C. The vessel contained a fatigue-sharpened notch adjacent to a half-bead ...
