In this paper, we prove the local exact null controllability of the thermoelastic plate model, in the absence of rotational inertia, and under the influence of the (non-Lipschitz) von Kármán nonlinearity. The plate component may be taken to satisfy either the clamped or higher order (and physically relevant) free boundary conditions. In the accompanying analysis, critical use is made of sharp o...

Introduction. The derivation of the mechanical behavior of a flat plate as the limit behavior of a three-dimensional flat solid whose thickness tends to zero is a well-established theory since the works of Goldenveizer [G] or Ciarlet and Destuynder [CD1], Due attention has been paid to the static response of such plates for various linear or nonlinear mechanical behaviors (Ciarlet-Destuynder [C...

During the braking action, the kinetic energy produced at the wheel is transformed into heat energy, which doesn’t dissipate fast enough into the air stream from the brake to the brake disk; as a result, the thermal conductivity plays a critical role in handling such heat generated. Thermal judder, which is a result of non-uniform contact cycles between the pad and the disk brake rotor, which i...

abstract objective: abnormal values of the transient ischemic dilation (tid) ratio are associated with severe and extensive coronary artery disease (cad). tid can be used as a diagnostic and prognostic marker of cad in diabetic patients. the aim of current study was to determine the pooled estimate of tid ratio in single myocardial perfusion scan in diabetic patients by a systematic review and ...

Thermography is becoming more and more relevant method in industry and as a research tool. It is an accepted method in many fields where non-destructive testing is carried out. In this paper focus was on evaluation of stress concentrations and fatigue of metal structures. Three thermographic methods: Thermoelastic stress analysis, Risitano method and acquisition of plastification zone and fract...

Thermoelastic loss is an important energy dissipation mechanisms in resonant systems. A careful analysis of the thermoelastic critical to design low-noise devices for high-precision applications, such as mirrors used gravitational-wave detectors. In this paper, we present analytical solutions due thermoelasticity between different materials that are contact. We find expressions multimaterial co...

The underlying working principle of detecting impulsive stimulated scattering signals in a differential configuration of heterodyne diffraction detection is unraveled by involving optical scattering theory. The feasibility of the method for the thermoelastic characterization of coating-substrate systems is demonstrated on the basis of simulated data containing typical levels of noise. Besides t...

The present article deals with the study of propagation of plane waves in isotropic generalized thermoelastic diffusion with voids under initial stress. It is found that, for two dimensional model of isotropic generalized thermoelastic diffusion with voids under initial stress, there exists four coupled waves namely, P wave, Mass Diffusion (MD) wave, thermal (T) wave and Volume Fraction (VF) wa...
