This talk presents the benefit of buckling in strongly tuning nonlinear MEMS resonators. In particular, shows experimental achieving more than 230% natural frequency drumhead Moreover, experiments demonstrate that switches response between purely stiffening, softening, and stiffening-to-softening nonlinearities. We tune state these by controlling electric voltage temperature Therefore, resonato...

A port-Hamiltonian formulation for general linear coupled thermoelasticity and the thermoelastic bending of thin structures is presented. The construction exploits intrinsic modularity systems to obtain a as an interconnection elastodynamics heat equations. derived model can be readily discretized by using mixed finite elements. discretization structure-preserving, since main features system ar...

<p style='text-indent:20px;'>We analyze the stability properties of a linear thermoelastic Timoshenko-Gurtin-Pipkin system with thermal coupling acting on both shear force and bending moment. Under either mixed Dirichlet-Neumann or else full Dirichlet boundary conditions, we show that associated solution semigroup in history space framework Dafermos is exponentially stable independently v...

In previous work, a series of theoretical considerations have been made aimed at identifying the source and assessing prominent factors influencing the thermoelastic response from laminated composites. In this paper four different methods of interpreting the data are investigated and the theoretical thermoelastic response is compared to experimental data to identify the source of the thermoelas...

Carbon fiber-reinforced plastic (CFRP) is widely used for structural members of transportation vehicles such as automobile, aircraft, or spacecraft, utilizing its excellent specific strength and specific rigidity in contrast with the metal. Short carbon fiber composite materials are receiving a lot of attentions because of their excellent moldability and productivity, however they show complica...

In the present article, we consider a thermoelastic plate of Reissner-Mindlin-Timoshenko type with the hyperbolic heat conduction arising from Cattaneo’s law. In the absense of any additional mechanical dissipations, the system is often not even strongly stable unless restricted to the rotationally symmetric case, etc. We present a well-posedness result for the linear problem under general mixe...
