RISFinite Element Analysis of Perforated Plates Containing Triangular Penetration Patterns of 5 and 10 Percent Ligament Efficiency
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two- and three-dimensional finite element models were used to determine elastic stress distributions in plate ligaments for various in-plane, bending, and thermal loadings. Plates containing ...
The Effect of Flaw Shape on the Fracture Propensity of Nozzle Corner Flaws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional finite element models were formulated to evaluate the distribution of the elastic stress intensity factor around the periphery of cracklike flaws postulated to exist at the ...
Gas Flow Resistance Measurements Through Packed Beds at High Reynolds Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research study indicates that the classical Reynolds number dependency of the coefficient of drag for gases forced into packed beds is not correct at high Reynolds numbers. Care must also ...
Elasto-Plastic Analysis of Perforated Plates Containing Triangular Penetration Patterns of 10 Percent Ligament Efficiency
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The finite element method is utilized to obtain the elasto-plastic stress and strain fields in a perforated plate made of a work-hardening material. The perforated plate contains penetrations ...
Local Flexibility Coefficients for the Built-in Ends of Beams and Plates Including the Effects of Foundation Fillet Radii
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The local deformations at the built-in end of a beam or plate re-entrant corner have considerable influence upon the redundant forces and moments at the juncture, and hence, upon the stresses. ...
Local Flexibility Coefficients for Axisymmetric Junctures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method of including the local flexibility due to cross-sectional warping at axisymmetric junctures is presented. Local flexibility coefficients are derived which have very general applicability ...
Elastic-Plastic Analysis of the PVRC Burst Disk Tests With Comparison to the ASME Code Primary Stress Limits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides a comparison between finite element analysis results and test data from the Pressure Vessel Research Council (PVRC) burst disk program. Testing sponsored by the PVRC over ...
Fatigue Crack Growth Testing of Sub-Clad Defects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue crack growth tests were performed on four-point bend specimens with cracklike defects intentionally placed in A302B low-alloy pressure vessel steel clad with 308/309L weld-deposited stainless ...
Elastic-Plastic Failure Analysis of Pressure Burst Tests of Thin Toroidal Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides a comparison between test and analysis results for bursting of thin toroidal shells. Testing was done by pressurizing two toroidal shells until failure by bursting. An ...
Residual Stresses in Weld-Deposited Clad Pressure Vessels and Nozzles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Results of through-thickness residual stress measurements are provided for a variety of samples of weld-deposited 308/309L stainless steel and Alloy 600 cladding on low-alloy pressure vessel ...
