ANALYSIS OF THERMAL STRESSES AND DISPLACEMENT IN A THICK ANNULAR DISC

Abstract

In this present work, a boundary value problem for thick annular disc subjected to thermal load with radiation type boundary conditions is solved. Some features of the stress and temperature distribution are investigated by means of Integral transform technique. Analytical expressions for the components of the displacement and temperature distribution vector that correspond to the stress state under the action of partial distribution are established. The result is obtained as series of Bessel functions. In addition a special case is discussed by taking the account to diametric compression of thick disc subjected to uniform pressure on opposite segments. In this stress distribution are investigated by theoretical technique. The above mentioned special case is developed by technique used by Yu. V. Tokovyy for determination of stress under diametral compression.
