An experimental study of the stress distribution around holes in orthotropic composite laminates has been conducted using thermoelastic stress analysis (TSA). Quantitative thermoelastic studies of stress concentrations in metallic plates is a straightforward matter, all that is required is the ratio of the response from the hole and a far-field reading. For orthotropic materials the situation i...

In the design of high Quality factor (Q) micro or nano beam resonators, different dissipation mechanisms may have damaging effects on the quality factor. One of the major dissipation mechanisms is the thermoelastic damping (TED) that needs an accurate consideration for prediction. In this paper, thermoelastic damping of the longitudinal vibration of a homogeneous micro beam with both ends clamp...

In this paper we study a one dimensional thermoelastic transmission problem of special string/beam structure: the two components are coupled at an interface (identified to $ 0 $). Either string or beam is supposed thermoelastic, heat flux given by Cattaneo's law instead usual Fourier's law. We prove that energy decay whole system exponential if thermoelastic. When only coupling decays polynomia...

Indroduction: The novel model of a non-local elastic semiconductor material that is microelongated created. process photothermal transfer responsible for the stimulation material. Photo-thermoelastic theories are used when thermal conductivity changed medium. Under influence laser pulses, effective framework describes nanoscale microelongation instance as well interference between photo-thermoe...

Abstract: In this paper we consider point control of a structural acoustic model with thermoelastic effects. The key feature of this paper is that the two-dimensional plate modeling the active wall of the acoustic chamber has clamped boundary conditions. For this case a new optimal regularity result has recently become available (Triggiani, 2008). Using this new result for the plate alone, we d...

The variability of thermoelastic stresses at the Earth’s surface is investigated on different scales with a three–dimensional numerical model. Energy transfer by heat conduction and radiation of sun, atmosphere and Earth’s surface is regarded. It is shown that thermoelastic stresses are considerably high, so that they are able to assist faulting and thus force weathering of rocks. Their morphol...

The thermoelastic effect was used to produce high-frequency, broadband ultrasound in water. A pulsed diode laser, followed by an erbium-doped fiber amplifier, was focused onto a light-absorbing film deposited on a glass substrate. Conversion efficiency was improved by over 20 dB using an elastomeric film instead of a more commonly used metallic one. Radiation pattern measurements show that cons...
