| Shrnutí: | Title screen This paper presents a computational analysis of the deformation and fracturemechanisms of a material with a porous polysilazane coating under tension and compression.A dynamic boundary-value problem in the plane strain statement is solved numerically by thefinite-difference method. The coating-substrate interface and porous coating microstructurecorresponded to configurations found experimentally are accounted for explicitly in thecalculations. For this purpose an algorithm for curvilinear finite-difference meshing based onthe solution of the elasticity theory has been developed. The algorithm implemented offersseveral benefits over the rectilinear meshing. Local regions experiencing bulk tension areshown to form along pore surfaces that control the fracture mechanisms at the mesoscale level.
