Turii O. Thermoelastic state of composite plate subjected to thermal radiation

A mathematical model to describe the thermoelastic state of plane-parallel plates (plate composites) subjected to thermal radiation is developed. It takes into account an effect of radiation on plate surfaces, contact boundaries and in semitransparent plate bulk. Within a framework of model the contact problems of heat transfer and thermoelasticity for plates consisting of two and three layers of a various transparency have been posed. The methods to solve new linear and nonlinear contact-boundaries problems of thermoelasticity are proposed. On analysing the posed problems solutions, the new features of temperature and stresses distributions in plates subjected to thermal radiation are established, dependent on the set of various factors, namely on radiative properties of layers, layer's thickness and on source temperature.
