Dynamics of sliding mechanisms in nanoscale friction
… inappropriate due to the small dimensions of the sliding elements and the lack of excessive plastic deformation. This thesis presents a theoretical investigation of friction at the sliding interface by Molecular Dynamics (MD) simulations of ideal Lennard-Jones solids. The effect of the interfacial …

Chemical and physical aspects of wear processes in polymers
… containing polymers have been studied whilst sliding against mild steel and oxides present on mild steel. The degradation characteristics of P. V. C. and C1d P. V. C. have been correlated in terms of current mechano-chemical comminution theory and the process causing the wear of P. V. C., C1d …

Nonlinear seismic analysis of quasi-isolation systems for earthquake protection of bridges
… are reduced and isolation is achieved by sliding of the bearings. The system is a pragmatic approach for providing earthquake resilient bridges in locations such as the eastern and central United States, as well as in many locations around the world where there is significant earthquake …

Validation of interpolative interfaces for rotorcraft applications
… in its own subdomain, and a nonmatching and sliding interface method is used to compute fluxes across the subdomain boundaries. Testing of the implementation of this method in Tenasi is the primary purpose of the study.

Interfacial Mechanics in Fiber-Reinforced Composites: Mechanics of Single and Multiple Cracks in CMCs
Several critical issues in the mechanics of the interface between the fibers and matrix in ceramic matrix composites (CMCs) are studied. The first issue is the competition between crack deflection and penetration at the fiber/matrix interface. When a matrix crack, the first fracture mode in a CMC, …

Dynamic Studies of Instability-Triggered Intersonic Surface Detachment Waves in Soft Material Sliding
… Among them, elastomeric materials sliding on smooth surfaces generate separation pulses due to tangential stress gradients. When the material slides at a speed much lower than those of elastic surface waves, the process is dominated by surface adhesion and relaxation effects coined …

Seismic response of structures with Coulomb damping
… of structures with various arrangements of sliding interfaces. First, three basic arrangements are studied for their effectiveness in reducing lateral displacements of the supporting frame, accelerations of the floor slab and the resulting secondary floor spectra. These are: (1) slab sliding …

An improved volumetric LBM boundary approach and its extension for sliding mesh simulation
… volumetric LBM boundary scheme is extended to sliding-mesh interface condition for flow simulation involving rotating geometries. A volumetric LBM sliding-mesh interface scheme couples the flow solutions on both sides of sliding interface, and conserves the mass and momentum flux across it. …

Progressive failure of slopes in lined waste impoundments
… failure occurs along displacement-softening interfaces. Sliding on such interfaces can occur in a progressive manner with the result that the available interface strengths are reduced below their peak values. The amount of strength reduction depends on the magnitude of shear displacement, …

Predicting lubrication performance between the slipper and swashplate in axial piston hydraulic machines
<p>Engineering of the sliding interfaces within swashplate type axial piston machines represents the most complex and difficult part of the design process. The sliding interfaces are subject to significant normal loads which must be supported while simultaneously preventing component wear to ensure …

Wear mechanisms of chemically crosslinked hydrogels under mild abrasion
… allowing them to efficiently maintain smooth sliding while under high compressive loads. As with any sliding interface under high loads, the hydrogels in this application would be highly susceptible to wear. While the fluid component of these materials mediates low friction sliding, the …

A time-spectral hybridizable discontinuous Galerkin method for periodic flow problems
… exploited in the development of a new high-order sliding mesh interface coupling technique for multiple-row turbomachinery problems. A regularization of the Spalart-Allmaras turbulence model is also employed to ensure numerical stability of unsteady flow solutions obtained with high-order methods. …
