Summary:	Title screen The multiscale hybrid discrete-continuous approach of excitable cellular automata was applied to account for the porosity and nanocrystalline structure when taking an idealized quasi-elastic thermal barrier coating as an object under simulation. The developed technique includes a set of algorithms for calculating the local moments of forces and angular velocities of micro-rotations occurring in a heterogeneous medium with regard to energy dissipation. It was found that at thermal cycling of polycrystalline system high level microstresses occurs resulting from the thermal expansion anisotropy of grains. The stress level was shown to decrease with increasing fraction of rotational modes. This tendency takes place over the entire depth of the studied specimen and during the entire thermal loading time. The simulation results indicate on the existence of an optimal porosity level when the structure exhibits the highest relaxation capacity. Режим доступа: по договору с организацией-держателем ресурса
