Abstract

Of interest here are dynamic thermoelastic problems influenced due to second sound effects. In this regard, the effect of the so called 'heat waves' on solid continua is investigated employing a 'unified' explicit computational architecture which uses the finite element method. The approach is robust and effective for transient interdisciplinary thermal-structural modeling analysis. The non-classical relaxation model of Green and Lindsay which is often referred to as the dynamic thermoelasticity theory involving two relaxation times and which does not violate the classical Fourier's model (if the material has center of symmetry at each point) is employed in the present work. Numerical simulations relevant to thermal shock problems in an elastic half-space are described, and the results presented are for stainless steel.
