Suppression of Stokes scattering and improved optomechanical cooling with squeezed light [PDF]
, 2016 We develop a theory of optomechanical cooling with a squeezed input light field. We show that Stokes heating transitions can be \emph{fully} suppressed when the driving field is squeezed below the vacuum noise level at an appropriately selected squeezing

New Micromechanics Design Theory for Pseudostrain Hardening Cementitious Composite [PDF]
Journal of Engineering Mechanics, 1999 The micromechanics design theory has realized random short fiber-reinforced cement composites showing pseudostrain hardening (PSH) behavior with over 5% of strain capacity under tension. Nevertheless, this existing theory currently is limited to specific constituent properties, which does not account for chemical bond and fiber rupture.

DEFORMATION BEHAVIOR OF NANO/MICRO REINFORCED PMMA [PDF]
, 2010 Práce sleduje vliv velikosti částic na elastický modul a deformační chování za mezí kluzu. Bylo pozorováno, že jak elastická oblast, tak oblast za mezí kluzu ukazuje silnou závislost chování na velikosti částic.

Jamming transition in emulsions and granular materials
, 2005 We investigate the jamming transition in packings of emulsions and granular materials via molecular dynamics simulations. The emulsion model is composed of frictionless droplets interacting via nonlinear normal forces obtained using experimental data ...

Interfacial strength in thermoplastic composites - at last an industry friendly measurement method? [PDF]
, 2001 Many elegant techniques have been developed for the quantification of composite micro-mechanical parameters in recent years. Unfortunately, most of these techniques have found little enthusiastic support in the industrial product development environment,

Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System
Advanced Materials, EarlyView.A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

Work fluctuations in a nonlinear micromechanical oscillator driven far from thermal equilibrium
, 2015 We explore fluctuation relations in a periodically driven micromechanical torsional oscillator. In the linear regime where the modulation is weak, we verify that the ratio of the work variance to the mean work is constant, consistent with conventional ...
