Some Aspects of Nonlinear Behavior in Lubricants Under Extreme Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general basis for discussing nonlinearity in the flow of molecular fluids consists in applying the continuum mechanics of Coleman and Noll to a flow process governed by an Arrhenius activation ...
Rolling Contact Lubrication—The Application of Elastohydrodynamic Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A series of experiments on measurements of friction between lubricated rollers moving in combined rolling and sliding is reviewed. The classes of phenomena that occur under various combinations ...
Part-Elliptical Cracks Emanating From Open and Loaded Holes in Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A linear elastic analysis using the finite element-alternating method is conducted for problems of single semi-elliptical and double quarter-elliptical cracks near fastener holes. Mode-one stress ...
Constituent Diffusion in a Deformable Thermoelastic Solid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solid mixtures containing initially uniform dilute concentrations of impurity elements may, upon the application of mechanical and thermal loading, develop regions of high impurity concentration ...
Stress-Intensity Factors for a Surface Crack in a Finite Solid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A solution to the problem of a circular crack partially embedded in a solid of finite thickness is presented. A superposition and iteration technique is used to determine the stress-intensity ...
The Elliptical Crack Subjected to Nonuniform Shear Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The equations of elasticity are solved for the problem of a flat elliptical crack which has nonuniform shear stresses applied to its surfaces. The shear stresses are prescribed independently ...
Quarter Elliptical Cracks Emanating From Holes in Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The finite element-alternating method, a linear elastic solution technique, is refined and applied to problems of quarter-elliptical cracks in irregular bodies. The method involves the iterative ...
Stress Intensity Factors for Penny-Shaped Cracks: Part 1—Infinite Solid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An expression is developed for the stress intensity factor of a penny-shaped crack in an infinite elastic solid subjected to nonaxisymmetric normal loading. The stress intensity factor can then ...
Stress Intensity Factors for Semicircular Cracks: Part 2—Semi-Infinite Solid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stress intensity factor for a semicircular edge crack is derived. Numerical values for axial, bending, and thermal loads in half spaces and plates are presented. The results show that a ...
Numerical Simulation of the Mechanically Coupled Cook-Off Experiment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There has been a significant amount of recent interest concerning the behavior of High Explosives including work on an experiment known as the Mechanically Coupled Cook Off experiment in which ...
