Effects of Prior Stress Relaxation on the Prediction of Creep Life Using Time and Strain Based Methods
(The American Society of Mechanical Engineers (ASME), 2013)A critical requirement for both next generation conventional and nuclear plants is the development of simplified inelastic design and fitness for purposes procedures that give a reasonably accurate prediction of the complex ... -
Equations to Calculate Collapse Strength for High Collapse Casing
(The American Society of Mechanical Engineers (ASME), 2013)As wells are drilled deeper, the external pressures applied to well casing become greater. Conventional America Petroleum Institute (API) casing strength cannot meet the strength criteria of high pressure, high temperature, ... -
Long Term Stability of Residual Stress Improvement by Water Jet Peening Considering Working Processes
(The American Society of Mechanical Engineers (ASME), 2013)To prevent primary water stress corrosion cracking (PWSCC), water jet peening (WJP) has been used on the welds of Nibased alloys in pressurized water reactors (PWRs). Before WJP, the welds are machined and buffed in order ... -
Optimizing Temper Bead Welding by Computational Weld Mechanics and Design of Experiment Matrix
(The American Society of Mechanical Engineers (ASME), 2013)Temper bead welding is usually done by experiment, i.e., trial and error. This paper describes a computational weld mechanics model to compute the transient temperature and transient microstructure evolution in temper bead ... -

Framework for a Combined Netting Analysis and Tsai Wu Based Design Approach for Braided and Filament Wound Composites
(The American Society of Mechanical Engineers (ASME), 2013)Axially symmetric fiberreinforced polymer composite structures, such as pressure vessels and piping, are being widely used in different industrial applications where combined loading conditions may be applied. It is ... -
Fatigue Crack Propagation Analysis of Repaired Pipes With Composite Patch Under Cyclic Pressure
(The American Society of Mechanical Engineers (ASME), 2013)The pipes in offshore and marine structures are mainly made of lowstrength structural steels such as A537 steel and are subjected to the effects of both corrosive medium and cyclic loading caused by many factors. Reinforcement ... -
Two Phase Flow Induced Forces on Piping in Vertical Upward Flow: Excitation Mechanisms and Correlation Models
(The American Society of Mechanical Engineers (ASME), 2013)Momentum variation in twophase flow generates significant low frequency forces, capable of producing unwanted and destructive vibrations in nuclear or petroleum industries. Twophase flowinduced forces in piping were ... -
On Simplified Inelastic Method Using Material's Isochronous Stress–Strain Data for Creep Analysis
(The American Society of Mechanical Engineers (ASME), 2013)Design of components or structures at elevated temperature is complex and the use of rigorous time dependent material models may not be practical for many large scale industrial problems. The use of simplified methods ... -
