In this paper, the quality factor of thermo-elastic damping in an electro-statically deflected micro-beam resonator has been investigated. The thermo-elastic coupled equations for the deflected micro-beam have been derived using variational and Hamilton principles based on modified couple stress theory and hyperbolic heat conduction model. The thermo-elastic damping has been obtained discretizi...

Given an instance I of a minimization problem with optimum opt, fixed parameter ρ(k) inapproximability is to find a k ≥ opt and prove that it is not possible to compute a solution of value ρ(k) · k. In this paper all proofs are under the eth, and we are interested only in k being the optimum value of some instance. Our question is: What properties make a good Fixed Parameter Inapproximability p...

In this paper a novel technique is presented to solve tolerance design problems. To achieve the desired performance tolerance the technique uses a subtle, but significant, change in the design rather than increasing component precision. This change is the addition of a tuning parameter. Statistical models are used to developed framework for the tuning parameter design method. Also developed is ...

this study presents exact bending solution of fully clamped orthotropic rectangular plates subjected to arbitrary loads resting on elastic foundations, based on the finite integral transform method. in this method, it is not necessary to determine the deformation function because the basic governing equations of the classical plate theory for orthotropic plates have been used. a detailed parame...

Abstract This paper proposes new analytical and finite element solutions for studying the effects of elastic foundations on uncontrolled controlled static vibration responses smart multi-layered laminated composite plates with integrated piezoelectric layers, acting as actuators sensors. A non-polynomial higher-order plate theory zigzag kinematics involving a trigonometric function local segmen...
