• On the basis of the variational formulation of thermoelasticity, a melting problem ofan elastic solid is discussed. Two variational invariants of thermoelasticity with phasechange are introduced and a variational equation is formulated. The method is entirelyvariational and does not require the evaluation of the temperature field. A parabolicapproximation of temperature field is used as a test function and an approxnmatedifferential equation of the melting line is formulated. Using Adams-Bashforth'smethod this equation provides a series solutton.
