Temperature strongly affects muscle contractile rate properties and thus may influence whole-organism performance. Movements powered by elastic recoil, however, are known to be more thermally robust than muscle-powered movements. We examined the whole-organism performance, motor control and muscle contractile physiology underlying feeding in the salamander Eurycea guttolineata. We compared elas...

left atrial (la) distension has been demonstrated to be linked with aortic stiffness in different patient populations. three-dimensional (3d) speckle-tracking echocardiography (ste) seems to be a promising tool for volumetric and functional evaluation of the la. the aim of the present study was to determine whether correlations exist between 3dste-derived la volume-based and strain parameter...

By using an iron alloy that transforms slowly to bainite at a low temperature, it has been possible to study the development of the upper bainite under the influence of exceptionally large stresses, which are nevertheless below the yield strength of the parent austenite. It is found that a uniaxial stress whose magnitude is below the elastic limit, strongly favours the growth of compliant varia...

The most important plastic resins used for wire coating are polyvinyl chloride (PVC), nylon, polysulfone, and low-/high-density polyethylene (LDPE/HDPE). In this article, the coating process is performed using elastic-viscous fluid as a coating material for wire coating in a pressure type coating die. The elastic-viscous fluid is electrically conducted in the presence of an applied magnetic fie...

In the present work, large deformation rate-dependent constitutive behavior of isotactic polypropylene is studied via an experimentally validated macroscale model. To analyze nonlinear response material, mechanical tests are conducted at room temperature and a phenomenological model proposed to describe viscoplastic yielding damage semicrystalline polymer. The based on finite elastic-viscoplast...

Electro-magneto-thermo-elastic response of a thick double-layered cylinder made from a homogeneous interlayer and a functionally graded piezoelectric material (FGPM) outer layer is investigated. Material properties of the FGPM layer vary along radius based on the power law distribution. The vessel is subjected to an internal pressure, an induced electric potential, a uniform magnetic field and ...

In this study we propose a unified multi-scale chemo-mechanical description of the BCT (Body-Centered Tetragonal) to BCC (Body-Centered Cubic) order-disorder transition in martensitic steel by adding the mechanical degrees of freedom to the standard CALPHAD (CALculation of PHAse Diagrams) type Gibbs energy description. The model takes into account external strain, the effect of carbon compositi...

An analysis of radiation and soret effect on visco-elastic mhd oscillatory flow with heat and mass transfer through a porous medium bounded by two infinite horizontal parallel porous plates in presence of chemical reaction and a heat source has been presented when one plate is kept at rest while the other is oscillating in its own plane. The fluid is considered to be non-Newtonian characterized...

In this article, surface stress and nonlocal effects on the biaxial and uniaxial buckling of rectangular silver nanoplates embedded in elastic media are investigated using finite difference method (FDM). The uniform temperature change is utilized to study thermal effect. The surface energy effects are taken into account using the Gurtin-Murdoch’s theory. Using the principle of virtual work, the...

In view of the increasing requirements on energy saving, as well as the necessity to cool the growing number of on-chip components, the alternative cooling principles not associated with the traditional refrigerants become more and more actual. The most promising are the solid-state cooling devices, among which are widely used systems based on the Peltier effect. However, due to the low refrige...
