%0 Journal Article %T Heat conduction: hyperbolic self-similar shock-waves in solids %A Imre Ferenc Barna %A Robert Kersner %J Physics %D 2012 %I arXiv %X Analytic solutions for cylindrical thermal waves in solid medium is given based on the nonlinear hyperbolic system of heat flux relaxation and energy conservation equations. The Fourier-Cattaneo phenomenological law is generalized where the relaxation time and heat propagation coefficient have a general power law temperature dependence. From such laws one cannot form a second order parabolic or telegraph-type equation. We consider the original non-linear hyperbolic system itself with the self-similar Ansatz for the temperature distribution and for the heat flux. As results continuous and shock-wave solutions are presented. For physical establishment numerous materials with various temperature dependent heat conduction coefficients are mentioned. %U http://arxiv.org/abs/1204.4386v1
