RISThe Effects of Plate Stress-Strain Behavior and Pipemaking Variables on the Yield Strength of Large-Diameter DSAW Line Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent stringent specifications for large-diameter double-submerged-arc-welded gas-transmission line pipe include requirements that limit the range of allowable pipe yield strengths instead of the ...
Invariant Imbedding Applied to Eigenvalue Problems in Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A formal method is presented for obtaining eigenvalues of ordinary differential equations associated with problems of buckling and vibration. The method utilizes the idea of invariant imbedding ...
Factors Influencing the Plane-Strain Crack Toughness Values of a Structural Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An investigation was conducted to determine the effects of the variables; temperature, strain rate, and precracking fatigue-stress level, on plane-strain crack toughness values of a rate and ...
Creep Rupture of Rotating Disks and Thin Shells of Revolution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical analysis is made of the time to rupture for steady-state creep of: (a) A rotating thin circular disk of arbitrary profile, and (b) a rotating thin hollow shell of revolution. ...
Notch-Ductility Transition of Structural Steels of Various Yield Strengths
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The notch-ductility transition of six structural steels, A36, ABS-Class C, A302-Grade B, HY-80, A517-Grade F, and HY-130, ranging in yield strength from 36 to 137 ksi, was studied with the use ...
Relationships Between Mechanical Properties and the Extension and Arrest of Unstable Cracks in Line Pipe Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increasing need for high-strength, high-pressure, large-diameter, gas-transmission lines, considerable attention has been given, in recent years, to the aspects of fracture initiation, ...
Methodology for Analyzing Ranges of Uncertain Model Parameters and Their Impact on Total Maximum Daily Load Process
Publisher: American Society of Civil Engineers
Abstract: A methodology for analyzing uncertain parameter ranges prior to model calibration or uncertainty analysis is presented. The method considers parameters that exist in complex models and are typically difficult to set using ...
Stochastic Assessment of Long-Term Impacts of Phosphorus Management Options on Sustainability with and without Climate Change
Publisher: American Society of Civil Engineers
Abstract: In this study, a combination of two modified versions of the SWAT 2005 model are used to estimate the impact of several best management practices on phosphorus loading to the Cannonsville reservoir in upstate New York as ...
Static and Dynamic Low-Temperature KIc Behavior of Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To determine the crack-toughness behavior of steels subjected to high strain rates, a study was undertaken to establish the effects of strain rate and temperature on the KIc -values of steels. ...
Displacement Consideration for a Ductile Propagating Fracture in Line Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To date, the technically complex problem of arriving at an analysis for a running shear fracture in a gas-transmission line pipe has been primarily viewed by investigators in terms of an ...
