RISMinimum Stress Design of Nozzles in Pressure Vessel Heads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the early design stage of pressure vessels the configuration of the piping systems is not yet established; hence forces transmitted by the piping systems to the nozzles in the pressure ...
Contact Between Vessel Shell and Welded Pad in Nozzle Reinforcement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the thin shell analysis of welded pad reinforced nozzles in pressure vessels, no contact between pad and vessel is often assumed. The significance of this contact force to the stress ...
Prediction of Fracture Appearance Transition Temperature of 2.25Cr-1Mo Steel Used in Hot-Wall Hydrofining Reactors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A kinetics model for temper embrittlement was employed as the basis for predicting the fracture appearance transition temperature (FATT) of 2.25Cr-1Mo steel used for hot-wall hydrofining reactors. ...
Flexibility of Trunnion Piping Elbows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Trunnion piping elbows are commonly used in piping systems in power and chemical plants. The flexibility of the trunnion piping elbows is normally less than that of the plain piping elbows. ...
Effects of Crack Depth, Specimen Size, and Out-of-Plane Stress on the Fracture Toughness of Reactor Vessel Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cleavage fracture toughness values for A533-B reactor pressure vessel (RPV) steel at -40°C obtained from test programs at Oak Ridge National Laboratory (ORNL) and University of Kansas (KU) ...
An Evaluation of Material Weight and Contained Fluid Volume for Eccentric Intersecting Cylinders of Arbitrary Size
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engineering personnel in industries which use pressurized containment vessels having attached nozzles are required not only to design portions of the lifting mechanism, but also to estimate the ...
Interferometric Determination of Curvatures of Flexed Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two interferometric techniques are proposed that can readily be applied to the measurement of stresses in thin plates. A point-by-point method is presented that allows the analyst to determine ...
Assessment of the Engineering Approach for the Evaluation of C-Shaped Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A baseline study has been carried out to assess the accuracy of the engineering approach for J -integral determination when applied to various standard specimens. Detailed finite element ...
Microindentation Test for Assessing the Mechanical Properties of Silicone Rubber Exposed to a Simulated Polymer Electrolyte Membrane Fuel Cell Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The elastomeric materials used as seals and gaskets in polymer electrolyte membrane (PEM) fuel cells are exposed to acidic environment, humid air, and hydrogen, and subjected to mechanical ...
Determination of Constraint-Modified J-R Curves for Carbon Steel Storage Tanks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mechanical testing of A285 carbon steel, a storage tank material, was performed to develop fracture properties based on the constraint theory of fracture mechanics. A series of single edge-notched ...
