Analytical Study on Fatigue Strength Reduction Factor of Small-Diameter Socket-Welded Pipe Joints
(The American Society of Mechanical Engineers (ASME), 1998)Four-point bending and rotating bending fatigue tests were conducted on socket-welded joints made of carbon, stainless, and Cr-Mo steels for clarification of the effects of diameter, welding pass ... -
Pipe Whip: In-Plane Whipping of Bent Cantilever Pipes
(The American Society of Mechanical Engineers (ASME), 1998)The dynamic elastic-plastic behavior of a bent cantilever pipe subjected to an in-plane force pulse at its tip is described. A theoretical model based on a large deflection formulation of ... -
Estimation of Residual Stresses in Hydraulically Expanded Tube-to-Tubesheet Joints
(The American Society of Mechanical Engineers (ASME), 1998)The knowledge of residual stresses introduced in the tubes of heat exchangers during their expansion in the tubesheet holes is important because of their effect on the structural integrity of ... -
Penetration and Perforation of Composite Sandwich Panels by Hemispherical and Conical Projectiles
(The American Society of Mechanical Engineers (ASME), 1998)The results of penetration and perforation tests carried out on composite sandwich panels with GRP skins and PVC foam cores using hemispherical-ended and conical-nosed indenters/projectiles under ... -
The Initiation of Environmentally Assisted Cracking in Semi-Elliptical Surface Cracks
(The American Society of Mechanical Engineers (ASME), 1998)A Criterion to predict under what conditions EAC would initiate in cracks in a high-sulfur steel in contact with low-oxygen water was recently proposed by Wire and Li (1996). This EAC initiation ... -
Effect of Tube-to-Tube Ties on Fluidelastic Instability of Tube Arrays Exposed to Crossflow
(The American Society of Mechanical Engineers (ASME), 1998)Tube-to-tube ties and their arrangement within the tube array are shown to affect the onset of fluidelastic instability. The influence of tie arrangement for a single tube row and for an ... -
A Simple Upper-Bound Method for Calculating Approximate Shakedown Loads
(The American Society of Mechanical Engineers (ASME), 1998)A simple approach for calculating upper-bound shakedown loads is described. The method is based on a series of iterative elastic finite element analyses (the elastic compensation procedure) applied ... -
The Creep Measurement of 475°C Pipeline Using Moire Interferometry
(The American Society of Mechanical Engineers (ASME), 1998)In this study, a new experimental method for measuring the creep of pipeline using moire interferometry was proposed. Curved-surface-deformed grating replicating technique was combined with the ... -
Experimental Study on Fatigue Strength of Small-Diameter Socket-Welded Pipe Joints
(The American Society of Mechanical Engineers (ASME), 1998)The authors conducted fully reversed four-point bending fatigue tests on socket-welded joints 20 to 50 mm in nominal diameter, and rotating bending fatigue tests on socket-welded joints 20 mm ... -
Riser-Relief Valve Dynamic Interactions (Extension to a Previous Model)
(The American Society of Mechanical Engineers (ASME), 1998)Further investigation of the dynamic stability behavior of a typical pilot-operated relief valve is reported. The present study is an extension to Botros et al. (1997) model, which includes ... -
Flexural Rigidity of Annular Flange Connections
(The American Society of Mechanical Engineers (ASME), 1998)In order to analyze the vibration of a structure whose elements are connected with bolts, it is necessary to estimate the flexural rigidity of bolted connections. Some studies have been reported ... -
Reliability Assessment of Mechanical Components Using Fuzzy-Set Theory
(The American Society of Mechanical Engineers (ASME), 1998)An approach to assessing the reliability of mechanical components, especially for pressure vessels and piping, is proposed in which the vagueness and fuzziness in variables have been considered. ... -
Vibration Damping in Multispan Heat Exchanger Tubes
(The American Society of Mechanical Engineers (ASME), 1998)Heat exchanger tubes can be damaged or fail if subjected to excessive flow-induced vibration, either from fatigue or fretting-wear. Good heat exchanger design requires that the designer understands ... -
Probability of Fracture and Life Extension Estimate of the High-Flux Isotope Reactor Vessel
(The American Society of Mechanical Engineers (ASME), 1998)The state of the vessel steel embrittlement as a result of neutron irradiation can be measured by its increase in ductile-brittle transition temperature (DBTT) for fracture, often denoted by ... -
Centrifugal Compressor Modifications and Their Effect on High-Frequency Pipe Wall Vibration
(The American Society of Mechanical Engineers (ASME), 1998)High-frequency pulsation generated by centrifugal compressors, with pressure wavelengths much smaller than the attached pipe diameter, can cause fatigue failures of the compressor internals, impair ... -
Accelerated Stress Rupture Testing for Creep Life Prediction—Its Value and Limitations
(The American Society of Mechanical Engineers (ASME), 1998)Accelerated stress rupture testing has become a common method for determination of the remaining life of in-service components subject to creep damage at elevated temperatures. Stress and temperature ... -
Fretting Wear Damage of Heat Exchanger Tubes: A Proposed Damage Criterion Based on Tube Vibration Response
