We consider a general mathematical model which describes the quasistatic contact of deformable body with an obstacle, so-called foundation. The material’s behaviour is modeled visco-elastic-type constitutive law and described interface associated to version Coulomb’s dry friction. list assumptions on data provide relevant examples laws boundary conditions. Then, we derive two different variatio...

An analysis of mixed convective MHD visco-elastic flow with heat and mass transfer from a vertical plate in presence of ohmic heating and viscous dissipation has been presented. The governing equations of the momentum, thermal and concentration fields are solved by perturbation technique. Expressions for velocity, temperature, concentration profiles and non-dimensional skin-friction coefficient...

In this research, static stresses analysis of boron nitride nano - tube reinforced composite (BNNTRC) cylinder made of poly - vinylidene fluoride (PVDF) subjected to non - axisymmetric thermo - mechanical loads and applied voltage is developed. The surrounded elastic medium is modelled by Pasternak foundation. Composite structure is modeled based on piezoelectric fiber reinforced composite (PFR...

Free vibration of a simply-supported magneto-electro-elastic doubly-curved nano-shell is studied based on the first-order shear deformation theory in the presence of the rotary inertia effect. To model the electric and magnetic behaviors of the nano-shell, Gauss’s laws for electrostatics and magneto statics are used. By using Navier’s method, the partial differential equations of motion are red...

Nonlocal vibration of double-smart nanobeam-systems (DSNBSs) under a moving nanoparticle is investigated in the present study based on Timoshenko beam model. The  two  smart  nanobeams (SNB) are  coupled  by  an  enclosing  elastic  medium  which  is  simulated  by  Pasternak foundation. The energy method and Hamilton’s principle are used to establish the equations of motion. The detailed param...
