Using  principle  of  minimum  total  potential  energy  approach  in conjunction  with  Rayleigh-Ritz  method,  the  electro-thermo- mechanical  axial  buckling  behavior  of  piezoelectric  polymeric cylindrical  shell  reinforced  with  double-walled  boron-nitride nanotube  (DWBNNT)  is  investigated. Coupling  between  electrical and mechanical  fields  are  considered  according  to  ...

In this paper, the finite volume method is developed to analyze coupled dynamic problems of nonlinear thermoelasticity. The major focus is given to the description of martensitic phase transformations essential in the modelling of shape memory alloys. Computational experiments are carried out to study the thermo-mechanical wave interactions in a shape memory alloy rod, and a patch. Both mechani...

This work reports on a novel magnetorheological polymer gel with carbon nanotubes and carbonyl iron particles mixed into the physical cross-linked matrix. The resulting composites show unusual nonlinear magneto-electro-mechanical responses. Because of low matrix viscosity, effective conductive paths formed by CNTs were mobile high-performance sensing characteristics observed. In particular, due...

In electrosurgery radiofrequency (RF, 300 KHz—3 MHz) alternating current (AC) is used to raise intracellular temperature in order to achieve cutting or coagulation of soft tissue [1]. The type of tissue effect (e.g. cutting or coagulation) is dependent on many factors, such as activation time and electrosurgical waveform properties. Thus, modeling electrosurgical procedure in soft tissue is con...

This work presents a study on the computational homogenization of electro-magneto-mechanically coupled problems through Virtual Element Method (VEM). VE-approaches have great potential for physical properties heterogeneous polycrystalline microstructures with anisotropic grains. The flexibility in element shapes can be exploited creating VE-mesh significant lower number degrees freedom if compa...

This study investigates that the sound wave propagation of multiferroic thermo elastic Nanofibers under the influence of surface effect and parametric excitation via Timoshenko form of beam equations. The equation of analytical model is obtained for Nanofiber through shear and rotation effect. The solution of the problem is reached through the coupled time harmonic equations in flexural directi...
