000003524 520__ $$2eng$$aThe development of temperatures in a surface layer of a massive body during short-term heating and the following free cooling can be modelled as unidirectional heat flow in a semiinfinite solid. For the heating of bodies with uniformly distributed temperature, analytical solutions exist, while for the cooling (starting from nonuniform temperature distribution), a numerical procedure must be used. The paper brings formulae for various conditions of heating and for the numerical solution of the heat flow equation. Their use is illustrated on a model of heating caused by mutual sliding of a railway wheel and a rail, and of the following cooling by free convection into air and conduction into the body.
