For purpose, Finite Element Method applied to analyze a generalized thermoelasticity theory with relaxation time. development of model, thermal conductivity dependent on temperature medium was considered. The boundary condition for internal surfac...

We analyze an inverse problem associated with the time-harmonic Rayleigh system on a flat elastic half-space concerning recovery of Lamé parameters in slab beneath traction-free surface. employ Markushevich substitution, while data are captured Jost function, and we point out parallels corresponding for Schrödinger equation. The function can be identified spectral data. derive Gel’fand-Levitan ...

This analytical study demonstrates shear elastic wave propagation in stratified waveguide with emphasis on localisation effects using the propagator matrix method. The consists of two-phase piecewise homogeneous periodically arranged finite number sub-layers along thickness. Analytical solutions are carried out for traction free waveguide. existence two modal types guided waves is established: ...

The main objective of this work is to study the homogeneous thermoelastic interactions in an isotropic hollow thin cylinder immersed electric–magnetic field using linear Moore–Gibson–Thompson theory thermoelasticity, taking into account generalized Ohm’s law. MGT system equations for new model created by incorporating a relaxation period Green–Naghdi type III framework. In addition, Maxwell tha...

PURPOSE To determine the topographic effects of zonular tension on the anterior surface of the human crystalline lens. METHODS Real-time topography of the anterior surface of seven fully relaxed, freshly extracted intact, clear, human crystalline lenses aged 3, 17, 45, 54, 54, 56, and 56 years was qualitatively obtained before, during, and after the application of zonular traction. Zonular tr...

Closed form expressions are developed for the thermoelastic curvature of the initially plane end faces of a traction free cylinder subjected to arbitrary axisymmetric heat flux, the curved surfaces being assumed insulated. The solution is developed from a potential function representation of displacement and temperature for an elastic layer. The reciprocal theorem is invoked to show that the tr...

Axisymmetric vibration of an infinite piezolaminated multilayer hollow cylinder made of piezoelectric layers of 6mm class and an isotropic LEMV Linear Elastic Materials with Voids layers is studied. The frequency equations are obtained for the traction free outer surface with continuity conditions at the interfaces. Numerical results are carried out for the inner, middle, and outer hollow piezo...

The aim of this study was to investigate the initial stability of mini-implants when placed slanting or perpendicular to the bone surface, and to examine the effects of differences in tractional direction. Titanium mini-implants were inserted into rabbit nasal bones, slanting (60 degrees , 120 degrees ) or perpendicular (90 degrees ) to the bone surface. These implants were then loaded with a f...

lar interactions and their local environment. Cell traction force microscopy (CTFM) was utilised to determine the exerted traction forces of individual cells on a coated elastic substrate. From knowledge of the elasticity of the gel (Young’s modulus) the displacement of the gel surface was used to calculate traction fields using finite element analysis (FEA). This initial data are being refined...

We report the results of a randomised trial to determine the effects of skin traction on 252 patients awaiting surgery for fractures of the proximal femur. They were allocated randomly to be nursed free in bed or to receive Hamilton-Russell skin traction. No differences were found between the groups in terms of pain suffered, analgesia required, frequency of pressure sores or ease of operation....
