An effective finite element modeling/analysis approach for dynamic thermoelasticity due to second sound effects

Of interest here are dynamic thermoelastic problems influenced by 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 (1972) involving two relaxation times is employed in the present work. Numerical simulations relevant to thermal shock problems in an elastic half-space are described for stainless steel via two different illustrative test cases.
