RISCritical Review of ASME III Plasticity Correction Factors for Fatigue Design-By-Analysis of Nuclear Power Plant Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Despite significant technological progress in recent years, elastic–plastic fatigue analysis of pressure-retaining components remains a time-consuming venture. Accordingly, nuclear pressure vessel design codes such as ASME ...
A Fully Implicit, Lower Bound, Multi Axial Solution Strategy for Direct Ratchet Boundary Evaluation: Implementation and Comparison
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ensuring sufficient safety against ratcheting is a fundamental requirement in pressure vessel design. However, determining the ratchet boundary using a full elasticplastic finite element analysis can be problematic and a ...
A Fully Implicit, Lower Bound, Multi Axial Solution Strategy for Direct Ratchet Boundary Evaluation: Theoretical Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ensuring sufficient safety against ratchet is a fundamental requirement in pressure vessel design. Determining the ratchet boundary can prove difficult and computationally expensive when using a full elastic–plastic ...
Investigating the Effects of Cyclic Thermo-Mechanical Loading on Cyclic Plastic Behavior of a Ninety-Degree Back-to-Back Pipe Bend System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pipe bends are generally employed for routing piping systems by connecting to straight pipes but back-to-back pipe bends are often necessary for confined space applications. In order to achieve safe operation under complex ...
