RISOn the Singular Eigenfunctions for Plane Harmonic Problems in Composite Regions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with the singular behavior of harmonic functions at the vertex of a plane, composite, wedge region. Separable harmonic functions which include logarithmic terms are ...
Logarithmic Stress Singularities Resulting From Various Boundary Conditions in Angular Corners of Plates in Extension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This note considers the in-plane loading of wedge-shaped plates comprised of a single, homogeneous and isotropic, linear elastic material. Several instances of logarithmic stress singularities ...
On the Breakdown Under Contact Conditions of Reynolds Equation for Gas Lubricated Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the analysis of gas lubricated bearings, Reynolds equation is available in a number of forms—the original version, first-order modified, second-order modified, one-and-a-half order modified, ...
Three-Dimensional Finite Element Analysis of Dovetail Attachments With and Without Crowning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stress analysis of dovetail attachments presents some challenges. These stem from the high stress gradients present, the contact inequalities attending conforming contact, and the nonlinearities ...
Towards a Reynolds Equation for Gas Lubricated Bearings When Contact Occurs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The various existing forms of Reynolds equation are known to yield pressure fields which are unbounded and nonphysical when contact occurs. With a view to developing a Reynolds equation that ...
Some Applications of Integrated Elasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines the effects of relaxing the assumption of classical linear elasticity that the loads act in their entirety on the undeformed shape. Instead, loads here are applied incrementally ...
On the Three-Dimensional Finite Element Analysis of Dovetail Attachments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stress analysis of dovetail attachments presents some challenges. These stem from the high stress gradients at the edges of contact. They also stem from the nonlinearities accompanying ...
On the Singularities in Reissner’s Theory for the Bending of Elastic Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wedge-shaped elastic plates under bending, with the edges forming the wedge vertex being either stress-free, clamped or simply supported, are characterized as to possible singular behavior within ...
Some Exact Solutions of Reynolds Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to check the numerical analysis of Reynolds equation for gas lubricated bearings, it is desirable to have available exact analytical solutions. This note outlines the construction of ...
Flash Temperature Distributions at the Head-Disk Interface in Hard Disk Drives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flash temperatures which can occur at a head-disk interface are simulated with a model which permits the two contacting surfaces to be of comparable roughness and recognizes the thermally ...
