RISResearch on Creep Behavior of Three-Point Bending Specimen With Fixed Constraints at the Large Deformation Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-point bending specimen with fixed constraints is a novel small specimen test technique, which can simultaneously obtain creep deformation and creep fracture data. However, the current research only focused on the ...
Residual Stress Distribution in Hard Facing of Pressure Relief Valve Seat
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, for the hardfacing of springloaded pressure relief valve seats, the residual stress distributions after the tungsten inert gas welding, (TIG) postwelded heat treatment and subsequent surface turning were ...
On Residual Stress and Relief for an Ultra-Thick Cylinder Weld Joint Based on Mixed Hardening Model: Numerical and Experimental Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Residual stress distributions as welded and after local postwelding heat treatment (PWHT) of butted weld joint of a huge cylinder with ultra-thick wall were investigated by finite element (FE) simulations and measurement. ...
Welding Residual Stress in HDPE Pipes: Measurement and Numerical Simulation
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: To understand the residual stress distribution in the welded joints of high density polyethylene (HDPE) pipes is essential to the assessment of its structural integrity. However, limited knowledge of their residual stress ...
Creep-Fatigue Behaviors and Life Assessments in Two Nickel-Based Superalloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this paper is to investigate different factors, including dwell time, strain range, and strain ratio on creep-fatigue endurances in nickel-based Inconel 718 and GH4169 superalloys. We also summarize classic ...
