THERMOELASTIC STRESSES IN MULTILAYER PLATES AND BASES,
Abstract
The article considers the problem of the state of stress of a multilayer plate which is under conditions of plane deformation, and which consists of m layers which have different mechanical and thermophysical properties not dependent on the temperature. On the free surfaces of the first and last layer the temperature is given as a function of the coordinate x sub k (steady state process) or as a function of the coordinate and the time (unsteady state process). The state of stress of a multilayer bundle on an elastic or rigid base can be obtained by infintely increasing the thickness of the last layer, h sub m approaches infinity. After setting the initial conditions, the authors solve mathematically the problem of funding the thermoelastic stresses due to steady state temperature fields, and then those due to unsteady state temperature fields.
