Abstract
Distribution of the transient temperature field and the corresponding quasi-static thermal stresses were examined in a system consisting of a bulk substrate and a thin coating of different material deposited on it. Such a system is heated through the outer surface of the coating by the pulsed heat flux generated due to absorption of laser pulse irradiation of rectangular or triangular time shape. The dependencies of temperature and stresses on geometric and thermophysical properties of the substrate and the coating were studied. It was proved that there is the possibility of applying the obtained results to modeling of thermal splitting for brittle materials.
This project was carried out as a part of a complex project no. S/WM/1/03 financed from a research budget line of Bialystok Technical University (BTU), Poland.
