S. Pidstryhach of the National Academy of Sciences of Ukraine popup.description2 Mathematical models of heat transfer in layered bodies with components of different radiation properties are proposed, taking into account the transfer of thermal radiation, as well as the stationary thermal and thermoelastic states of thermosensitive multilayer plates under high temperature heating. With their use, formulations were made and methods for solving the problems of thermomechanics for irradiated layered plates (in particular, coated plates) and for the study of the thermal and stress states of coated bodies with dry friction were developed. Numerical studies of temperature and stress in multilayer cylindrical plates and in a plate with dry friction coating were performed. Mathematical models for determining the phase components in a coated steel plate under high-temperature heating and subsequent cooling, as well as heating-cooling to find the thermal state of bodies of simple geometric shape under various kinds of high-intensity heating. The phase composition in a coated steel plate is studied and its physical and mechanical properties are predicted. Methods for predicting the appearance, location and development of zones of structural-phase transformations in bodies of simple geometric shape have been developed.   Product Description popup.authors Ivas'ko Roman O.
