RISSurface to Through-Wall Crack Transition Model for Circumferential Cracks in Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, finite element (FE) analyses were performed to update and also extend the applicable ranges of the existing KI and crack-opening displacement (COD) solutions for nonidealized through-wall cracks (TWCs). Then, ...
Engineering Approach Based on Reference Stress Concept for Calculating J and Crack Opening Displacement of Complex-Cracked Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, an engineering approach for estimations of fracture mechanics parameters, i.e., J-integral and crack opening displacement (COD), for complex-cracked pipes was suggested based on reference stress concept, ...
Finite Element Plastic Limit Loads of Complex Cracks in Pipes With Two-Layered Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the detailed three-dimensional (3D) finite element (FE) limit analyses, the present study investigates the plastic limit loads of complex-cracked pipes with two-layered materials for determining maximum load-carrying ...
Technical Basis for Flaw Acceptance Criteria for Cast Austenitic Stainless Steel Piping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: According to the current ASME Code Section XI, IWB-3640 and Appendix C flaw evaluation procedure, cast austenitic stainless steel (CASS) piping with ferrite content (FC) less than 20% is treated as wrought stainless steel. ...
