Identification of the thermal and thermostressed states of a two-layer cylinder from surface displacements

The problem of identifying the law of time variation in the temperature of one boundary surface of a two-layer cylinder and its thermal and thermostressed state from the temperature and radial displacement of the other surface is formulated and solved. The inverse problem of thermoelasticity to which the problem posed is reduced is analyzed for well-posedness. The solution of the direct problem of thermoelasticity is used to numerically test the technique of solving the inverse problem __________ Translated from Prikladnaya Mekhanika, Vol. 44, No. 1, pp. 40–47, January 2008.
