RISElasto-Plastic Finite Element Analysis of Repeated, Two-Dimensional Rolling-Sliding Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stresses, strains, and deformations produced by repeated, two-dimensional rolling-sliding contact are analyzed using a modified finite element model developed by Bhargava et al. [1]. Rolling ...
The Effects of Indent Residual Stresses on Mixed Mode Cyclic Crack Growth Driving Forces for Bearing Inner Rings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The residual stresses produced by plastic dents in a solid cylinder have been evaluated for overload, peak-contact-pressure-to-shear-strength ratios of p oi /k = 3.5, and p oi /k = 4. The ...
Influence of Indent Geometry on Repeated Two-Dimensional Rolling Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A “two-body,” elasto-plastic finite element model is employed to simulate repeated rolling contact in the presence of a surface irregularity. It is shown that the maximum Mises stress and ...
The Effect of Dent Size on the Pressure Distribution and Failure Location in Dry Point Frictionless Rolling Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite element simulation is performed for rolling contact over four different size spherical dents. Two rolling contacts are simulated using a portion of a sphere as a counter-face to the ...
Influence of Interference and Clamping on Fretting Fatigue in Single Rivet-Row Lap Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Primary fretting fatigue variables such as contact pressure, slip amplitude and bulk cyclic stresses, at and near the contact interface between the rivet shank and panel hole in a single ...
An Elastic-Plastic Finite Element Model of Rolling Contact, Part 1: Analysis of Single Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a two-dimensional (plane strain) elastic-plastic finite element model of rolling contact that embodies the elastic-perfectly plastic, cycle and amplitude-independent material of ...
Elasto-Plastic Coupled Temperature-Displacement Finite Element Analysis of Two-Dimensional Rolling-Sliding Contact With a Translating Heat Source
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper, describes a transient translating elasto-plastic thermo-mechanical finite element model to study 2-D frictional rolling contact. Frictional two-dimensional contact is simulated by ...
An Elastic-Plastic Finite Element Model of Rolling Contact, Part 2: Analysis of Repeated Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents finite element analyses of two-dimensional (plane strain), elastic-plastic, repeated, frictionless rolling contact. The analysis employs the elastic-perfectly plastic, cycle and ...
Optimal Discretization of Power Stress-Strain Law Curves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A criterion for optimal discretization of power stress-strain law curves is proposed. The criterion is based on the assumption that it is desirable to have the fewest possible line segments ...
Thermal-Mechanical Modelling of the Rolling-Plus-Sliding With Frictional Heating of a Locomotive Wheel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper examines finite element models for studying the long time frictional heating of locomotive wheels. The aim is to obtain the temperature distribution and the thermal and residual ...
