An analysis of free convective MHD visco-elastic fluid flow with heat and mass transfer over a vertical plate moving with a constant velocity in presence of Dufour and Soret effects has been presented. The fluid is considered to be non-Newtonian characterized by Walters liquid (Model B′). The surface temperature is assumed to oscillate with small amplitude about a non-uniform mean temperature. ...

Miguel Molerón, Marc Serra-Garcia, Chiara Daraio Department of Mechanical and Process Engineering, Swiss Federal Institute of Technology (ETH), Zurich, Switzerland (Dated: November 19, 2015) Abstract We theoretically and experimentally investigate visco–thermal effects on the acoustic propagation through metamaterials consisting of rigid slabs with subwavelength slits embedded in air. We demons...

The determination of subject-specific model parameter values is necessary in order for a computer simulation model of human motion to be evaluated quantitatively. This study used an optimisation procedure along with a kinematically-driven simulation model of the contact phase in running jumps to determine the elastic parameters of segmental wobbling masses and the foot-ground interface. Kinetic...

This study combines the isogeometric approach (IGA) and refined plate theory (RPT) with two variables to investigate buckling behavior of magneto-electro-elastic (MEE) foam plates resting on an elastic foundation. The pores in MEE are arranged three patterns: uniform, symmetric, asymmetric distributions across thickness. foundation supported by Winkler Pasternak is utilized computational model....

An essay by Belarusian children’s writers Andrei Zhvalevskyi and Evgenia Pasternak describes the experience of teaching literary skills in workshop “Literature with Authors” (“LISA”), opened 2016 Minsk, as well other educational programmes. The main trainees course are adolescents aged 12–17. authors review write about objectives workshop, methods peculiarities organisation studies, updating th...

The forward scattering series is an important and useful tool in constructing perturbative solutions to wave equation and understanding their relationship to their non-perturbative counterparts. When it converges, the series describes the total wavefield everywhere in a given medium as propagations in a reference medium and interactions with point scatterers. The method can be viewed as constru...

A method is proposed to identify the mechanical properties of the skin and core materials of sandwich structures having heterogeneous cores. All the elastic coefficients and loss-factors that matter in the dynamics of such a panel in the thick-plate approximation are identified. To this end, experimental natural modes (i.e. eigenmodes of the damped system) are compared to the numerical modes of...

A simple model presented here is to study the thermal effect on vibration of non-homogeneous orthotropic visco-elastic rectangular plate of parabolically varying thickness having clamped boundary conditions on all the four edges. For non-homogeneity of the plate material, density is assumed to vary linearly in one direction. Using the separation of variables method, the governing differential e...

Based on the nonlocal Timoshenko beam theory, the dynamic stability of functionally gradded (FG) nanoeams under axial load is studied in thermal environment, with considering surface effect. It is used power law distribution for FGM and the surface stress effects are considered based on Gurtin-Murdoch continuum theory. Using Von Karman geometric nonlinearity, governing equations are derived bas...
