The Effect of the Distance From the Center of a Weld to the Fixed End on the Residual Stress and Stress Intensity Factor of a Piping Weld
(The American Society of Mechanical Engineers (ASME), 2009)The fixed conditions of butt welds between straight pipe and the valves or pump in an actual piping system are different from those of straight pipes. However, the effect of the fixed condition ... -
Plastic Collapse Load for Vessel With External Flaw Simultaneously Subjected to Internal Pressure and External Bending Moment: Experimental and FEA Results
(The American Society of Mechanical Engineers (ASME), 2009)This paper is based on work done to establish the validity of a simple engineering approach to assess plastic collapse for a vessel with a local thin area (LTA). The approach is based on ... -
Residual Stress in an Autofrettaged Tube Taking Bauschinger Effect as a Function of the Prior Plastic Strain
(The American Society of Mechanical Engineers (ASME), 2009)Autofrettage is a practical method for increasing the elastic carrying capacity and the fatigue life of thick-walled cylinders such as cannon and high-pressure tubular reactor. Many analytical ... -
Development of Maximum Secondary Creep Strain Method for Lifetime of HDPE Pipes
(The American Society of Mechanical Engineers (ASME), 2009)Considering only the primary and secondary creep stages of high-density polyethylene (HDPE) material, a maximum secondary creep strain method (MSCS) and formula to calculate the maximum secondary ... -
Prediction of Fully Plastic Collapse Stresses for Pipes With Two Circumferential Flaws
(The American Society of Mechanical Engineers (ASME), 2009)Fully plastic collapse stress for a single circumferential flaw on a pipe is evaluated by the limit load criteria in accordance with the JSME Code S NA-1-2004 and the ASME Code Section XI. ... -
Cyclic and Fatigue Behavior of the P355NL1 Steel Under Block Loading
(The American Society of Mechanical Engineers (ASME), 2009)Current fatigue analyses of metallic structures undergoing variable amplitude loading, including pressure vessels, are mostly based on linear cumulative damage concepts, as proposed by Palmgren and ... -
Reliability-Based Design and Assessment Standards for Onshore Natural Gas Transmission Pipelines
(The American Society of Mechanical Engineers (ASME), 2009)Onshore pipelines have traditionally been designed with a deterministic stress-based methodology. The changing operating environment has, however, imposed many challenges to the pipeline industry, ... -
Circulation in Blowdown Flows
(The American Society of Mechanical Engineers (ASME), 2009)The blowdown (rapid release) of high pressure gas from a pressure vessel adiabatically cools the gas remaining in the vessel. The gas near the wall is warmed by conduction from the wall, ... -
The Fabulous Nuclear Odyssey of Belgium
(The American Society of Mechanical Engineers (ASME), 2009)This paper reviews the Belgian history of nuclear technology and its use for power generation, from the beginning in 1942 until now. It identifies the main players in the field, and the major ... -
Leakage Predictions for Static Gasket Based on the Porous Media Theory
(The American Society of Mechanical Engineers (ASME), 2009)In the present work, the annular static gaskets are considered as porous media and Darcy’s law is written for a steady radial flow of a compressible gas with a first order slip boundary ... -
Mechanical Analysis and Optimal Design for Carbon Fiber Resin Composite Wound Hydrogen Storage Vessel With Aluminum Alloy Liner
(The American Society of Mechanical Engineers (ASME), 2009)The carbon fiber resin composite (CFRC) wound high-pressure vessel is the key equipment of high-pressure hydrogen storage technology. High pressure includes high energy in operation, so it is ... -
New Developments for the Description of Oil Leakages by Advective Migration From Submarine Pipelines
(The American Society of Mechanical Engineers (ASME), 2009)The significant growth in offshore operations increases the risk of a pipeline rupture, even considering the high standards of safety involved. Throughout a submarine leakage, four different ... -
