In this work, an analytical solution for thermoelastic waves in a metal induced by an ultrafast laser pulse was formulated in the form of a Fourier series. The two-step heat transfer model was applied to account for the thermal nonequilibrium between electrons and the lattice during ultrafast pulsed laser heating. The coupling between the strain rate and the temperature ®eld was also considered...

SUMMARY The paper presents a new methodology for identifying sub-surface damage in composite components using a combination of Pulse Phase Thermography (PPT) and Thermoelastic Stress Analysis (TSA).

The friction clutch is considered a very important element of machines, as it plays major role in transferring power from the driving part to driven part. A common application vehicles connect between gearbox and engine. Fast wear occurs result frictional heating that generated when starting engage. This wear, addition high thermal stresses, will lead premature failure contacting surfaces. pres...

The work deals with a macroscopically isotropic energetic material based on triamino-trinitrobenzene (TATB) crystals bonded small volume fraction of thermoplastic polymer. This is shown experimentally to display an irreversible thermal expansion behavior characterized by dilatancy and variations its coefficient when heated or cooled outside narrow reversibility temperature range. analysis cooli...

The governing equations of an initially stressed, rotating and transversely isotropic thermoelastic solid permeated with magnetic field are solved for surface wave solutions. The appropriate particular solutions in the half-space satisfy the required boundary conditions at a thermally insulated stress free surface. A velocity equation is obtained for wave speed of thermo-elastic Rayleigh wave. ...

If two thermally conducting bodies are in sliding contact, the frictional heat generated at the interfaces causes thermoelastic distortion which profoundly influences the extent of the contact area and the distribution of contact stress [1]. This phenomenon now known as thermoelastic instability has been observed experimentally in a wide range of practical sliding systems [2, 3]. Several theore...

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...

The equations of coupled thermoelasticity are considered in the case of stationary vibrations. The dimensional and order-of-magnitude analysis of the parameters occurring within these equations prompts the introduction of the new non-dimensionalisation scheme, highlighting the nearly-adiabatic nature of the resulting motions. The departure from the purely adiabatic regime is characterised by a ...
