Viscoelastic material at high temperature is subjected to a cooling process. The stresses built up in the body are determined from a system of equations containing a strongly temperature‐dependent viscosity η ( T ), where the temperature T is given by the heat conduction equation. It is shown that for simple geometries such as infinite cylinders and spheres, the basic equations can be reduced to a single Volterra‐type integrodifferential equation, which is shown to have a unique solution.
