Abstract

This paper examines two metrics of frictional coupling, which are then used to predict how sensitive a frictional contact’s steady-state behavior is to its initial conditions. Based on a large set of numerical simulations with different contact geometries, material combinations, and friction coefficients, a contact’s sensitivity to initial conditions is found to be correlated with the product of the coupling metric and the friction coefficient. For cyclic shear loading, this correlation is maintained for simulations with different contact geometries, material combinations, and friction coefficients. However, for cyclic bulk loading, the correlation is only maintained when the contact edge angle is held constant.

Sensitivity analysis of frictional contact response of axisymmetric composite structures

Journal Article Karaoglan, L ; Noor, A K - Computers and Structures

A computational procedure is presented for evaluating the sensitivity coefficients of the static frictional contact response of axisymmetric composite structures. The structures are assumed to consist of an arbitrary number of perfectly bonded homogeneous anisotropic layers. The material of each layer is assumed to be hyperelastic, and the effect of geometric nonlinearity is included. The sensitivity coefficients measure the sensitivity of the response to variations in different material, lamination and geometric parameters of the structure. A displacement finite element model is used for the discretization. The normal contact conditions are incorporated into the formulation by using a perturbed Lagrangian approachmore »« less

Surface segregation of sulfur during oscillatory pin-on-plate wear studies of precious metal electrical contact alloys: I. Friction and electrical contact resistance

Conference Vook, R W ; Pope, L E ; Rohde, R W

An oscillatory pin-on-plate experimental configuration was used to investigate friction and electrical contact resistance phenomena of a gold base (ASTM B541) and a palladium base (ASTM B540) alloy couple. Effects which could be attributed to surface segregation were noted. Measurements were made in controlled environments of dry helium, dry carbon dioxide and dry air at atmospheric pressure. A load cell was used to measure the friction force continuously. No lubrication was employed. A U-shaped pin was used with electrical connections to measure electrical contact resistance for both forward and reverse direct currents. Friction coefficients were initially high but decreased tomore »« less
Software Quality Metrics for Geant4: An Initial Assessment - Paper 122

Conference Ronchieri, Elisabetta ; Giacomini, Francesco ; Pia, Maria Grazia

In the context of critical applications, such as shielding and radiation protection, ensuring the quality of simulation software they depend on is of utmost importance. The assessment of simulation software quality is crucial both to determine its adoption in experimental applications and to guarantee reproducibility of outcome over time. Geant4 is a simulation system used in a wide range of experimental applications, some of which, such as radiation protection and biomedical studies, may involve critical use cases and would especially profit from an objective assessment of the software quality. In this study, we present the first results from an ongoingmore »« less
Elevated temperature contact creep and friction of nickel-based superalloys using machine learning assisted finite element analysis

Journal Article Salari, Sepehr ; Behnia, Farnaz ; Polycarpou, Andreas A. ; ... - Mechanics of Materials

Nickel-based superalloys with superior thermochemical, mechanical, and tribological properties are highly utilized for critical components in several high temperature applications such as gas turbines and nuclear reactors. Inconel 617, in particular, is considered as one of the main candidate superalloys for tribo-components in very-high-temperature gas-cooled nuclear reactors. Recent findings indicate that this alloy grows unique surface oxide especially in a high-temperature helium environment with distinctive wear, friction, and contact properties. Here, this study investigates the high temperature contact area evolution and frictional behavior of Inconel 617 using finite element simulation and provides predictive models for the contact and friction performancemore »« less

Modeling of friction contact and its application to the design of shroud contact

Journal Article Yang, B D ; Menq, C H - Journal of Engineering for Gas Turbines and Power

Designers of aircraft engines frequently employ shrouds in turbine design. In this paper, a variable normal load friction force model is proposed to investigate the influence of shroudlike contact kinematics on the forced response of frictionally constrained turbine blades. Analytical criteria are formulated to predict the transitions between stick, slip, and separation of the interface so as to assess the induced friction forces. When considering cyclic loading, the induced friction forces are combined with the variable normal load so as to determine the effective stiffness and damping of the friction joint over a cycle of motion. The harmonic balance methodmore »« less
