Results of thermomechanical modelling of moving discontinuities in heterogeneous solids are discussed. Attention is focused on the velocity of the discontinuity which cannot be calculated by means of standard thermomechanical conservation laws. The corresponding kinetic relations for phase transition fronts and straight through crack propagation are derived on the basis of the material description of continuum mechanics and the thermodynamics of discrete systems.
