With the extensive applications of micro/nano-electro-mechanical systems, a great deal attention has been paid to explore influences arising size-dependent effect and surface on their performance. Along with these effects, nonlocal elasticity, strain gradient theory, elasticity theory were successively proposed. Moreover, it is inevitable for MEMS/NEMS work in variable temperature environment, correspondingly, thermal-induced stress or deformation becomes another issue that needs serious...
A theoretical thermo-magneto-electric (TME) bilayer model is established based on the Hamilton principle, in which both surface effect and flexoelectricity are all taken into account. The governing equations proposed with aid of nonlinear constitutive relations giant magnetostrictive materials. These general, can be applied to analyze coupled extensional, shear bending deformations at macroscale nanoscale. As a specific example, extensional motion slender beam suffering from external...
Thermoelastic buckling of micro/nano-beams subjected to non-uniform temperature distribution is investigated in this paper. The mechanical governing equation derived based on the surface effect and non-local effect. heat conduction model used predict micro/nano-beams. Therefore, obtained analytical solution can be analyze influence both thermal small scale effects thermoelastic In numerical simulations, a critical thickness proposed determine region effects. must considered if beam less than...
In the context of theory generalized thermoelastic diffusion, a two-dimensional electromagneto-thermoelastic problem with diffusion for half-space is investigated. The placed in an external magnetic field constant intensity and its bounding surface subjected to thermal shock chemical potential shock. governing equations are formulated solved numerically by means finite element method. derived directly time domain. nondimensional temperature, displacement, stress, potential, concentration...
Based on the generalized piezoelectric-thermoelastic theory, performance of imperfect interface dynamic response an infinite extent piezoelectric plate excited by thermal shock is presented. As a simple case, we first investigate behaviors single-layered which traction free and applied shock. After that double-layered with studied, same boundary conditions are adopted its external surfaces as used plate. The Laplace transform Riemann-sum approximation method utilized to solve coupled...
