Substrate constraints and interfacial boundary layers in thin polystyrene films are explored with high strain rate indentations characteristic of thermomechanical terabit data storage operations. Under these impact-like conditions, the coupling of strain-rate and inertial effects leads to large plastic deformations relative to quasi-static indentations. Strain shielding is present when the plas...

Nonequilibrium molecular dynamics simulations are reported at different strain rates (gamma) and thermodynamic state points for a shearing atomic fluid interacting via a Lennard-Jones potential. Our simulations are performed at the Lennard-Jones triple point, a point midway between the triple point and the critical point, and a high point closer to the critical temperature. We find that, for th...

In this paper, we use ideas from fractional calculus to study the rheological response of soft materials under steady-shearing flow conditions. The linear viscoelastic properties many multi-scale complex fluids exhibit a power-law behavior that spans over orders magnitude in time or frequency, and can accurately describe rheology using constitutive models. By measuring non-linear during large s...

In many cases, redundant systems are beset by both independent and dependent failures. Ignoring dependent variables in MTBF evaluation of redundant systems hastens the occurrence of failure, causing it to take place before the expected time, hence decreasing safety and creating irreversible damages. Common cause failure (CCF) and cascading failure are two varieties of dependent failures, both l...

The well-known mechanisms of interaction between precipitates and dislocations are shearing (for shearable precipitates) bypassing nonshearable precipitates). transition from to in precipitation hardening alloys leads changes dislocation motion mode multiplication behavior, which inevitably causes different PLC behaviors. In this study, we systematically investigate the influence Al3(Sc, Zr) on...

A quantitative trait loci (QTL) analysis of wool traits from experimental half-sib data of Merino sheep is presented. A total of 617 animals distributed in 10 families were genotyped for 36 microsatellite markers on four ovine chromosomes OAR1, OAR3, OAR4 and OAR11. The markers covering OAR3 and OAR11 were densely spaced, at an average distance of 2.8 and 1.2 cM, respectively. Body weight and w...
