A Three-Dimensional Thermomechanical Model of Contact Between Non-Conforming Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A necessary step in understanding failure problems of tribological elements is to investigate the contact performance of rough surfaces subjected to frictional heating. It is essential that the ...
Studying Contact Stress Fields Caused by Surface Tractions With a Discrete Convolution and Fast Fourier Transform Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The knowledge of contact stresses is critical to the design of a tribological element. It is necessary to keep improving contact models and develop efficient numerical methods for contact ...
Elastic Fields due to Eigenstrains in a Half-Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engineering components inevitably encounter various eigenstrains, such as thermal expansion strains, residual strains, and plastic strains. In this paper, a set of formulas for the analytical ...
Transient Thermoelastic Stress Fields in a Half-Space
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computing the thermoelastic stress field of a material subjected to frictional heating is essential for component failure prevention and life prediction. However, the analysis for three-dimensional ...
Three-Dimensional Semiperiodic Line Contact–Periodic in Contact Length Direction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Line contact problems, such as those seen in spur gears and cam-roller follower systems, are often simplified with the plane-strain assumption and thus modeled by two-dimensional equations. ...
A Three-Dimensional Thermal-Mechanical Asperity Contact Model for Two Nominally Flat Surfaces in Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rough surface contact in a tribological process involves frictional heating and thermoelastic deformations. A three-dimensional thermal-mechanical asperity contact model has been developed, which ...
Transient Three-Dimensional Solution for Thermoelastic Displacement Due to Surface Heating and Convective Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In tribological contact, frictional heating may lead to temperature rise, which in turn may result in thermal displacement of the contacting bodies. The quantification of these effects is desirable ...
Analytical Solution to the Hydrodynamic Lubrication of Fan-Shaped Thrust Step Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Step bearings are frequently used in industries for better load capacities. Analytical solutions to the Rayleigh step bearing and a rectangular slider with a finite width are available in ...
A Simple Method to Calculate Contact Factor Used in Average Flow Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The average flow model proposed by Patir and Cheng offers a great convenience for the analysis of rough surfaces in lubrication. The contact factor introduced by Wu and Zheng helps to solve ...
A Fast and Effective Method for Transient Thermoelastic Displacement Analyses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Frictional heating due to the relative motion of contacting surfaces causes temperature rise and thermal distortion, which in turn affects the contact geometry and pressure distribution. A fast ...
