Effect of stick-slip on magneto-rheological elastomer with a magnetic field
Friction, 2017 This study investigated the stick-slip characteristics of a magneto-rheological elastomer (MRE) against an aluminum plate. Herein, the MRE was manufactured, and a stick-slip tester was employed to evaluate the stick-slip performance of the MRE under ...

Dynamic Model and Quantitative Analysis of Stick-Slip Vibration in Horizontal Well
Shock and Vibration, 2020 Stick-slip is very harmful to the service life of drillstring. The extended Hamilton principle is applied in the paper. Then, finite element method (FEM) is employed to describe the model.

Decomposition of Velocity Gradient into Interparticle Slip and Rolling
Soils and Foundations, 1984 ABSTRACT Some of the best existing constitutive models for granular materials are based on the microkinematic assumption that the velocity gradient is a direct result of interparticle slip. For instance in the stress-dilatancy theory (Rowe, 1962, 1971) and in the double sliding, free rotating model (de Josselin de Jong, 1971, 1976, 1977 a, b) the ...

Advanced Engineering Materials, EarlyView.Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Processing and fluid flow characteristics of hot isostatically pressed porous alumina for aerostatic bearing applications [PDF]
, 1996 Despite their well known superior load and stiffness characteristics, the wide-spread use of porous aerostatic bearings in preference to other bearing types has been hampered by difficulties in controlling the permeability of the porous material during

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Direct Numerical Simulation of Turbulent Channel Flow with Spanwise System Rotation and Velocity Slip on Suction Wall [PDF]
Journal of Applied Fluid MechanicsDirect numerical simulations are conducted to investigate the turbulent flow of an incompressible Newtonian fluid in a channel at a fully-developed state. The channel rotates steadily around its spanwise axis.

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...
