• On the basis of the variational formulation, a problem of ablation of elasticsolid is discussed. A melting elastic rod is insulated at one end and exposed to aprescribed heat input at the other end and at the latter end the ablation occurs.A thermal potential and a dissipation function are introduced as variationalinvariants, and a variational equation is derived by use of the differential equationof thermoelasticity and the boundary condition of ablation. Using a parabolicformula as a test function, an approximate differential equation of melting lineis derived. With the aid of Adams-Bashforth's method a series solution of theposition of the melting line is found.
