Mathematical modeling of thermoelastic deformation of asymmetric fragment of nitride ceramic surface layer

As a result of numerical experiments, the regularities of thermoelastic deformation of the surface layer of nitride ceramics, presented in the form of an asymmetric fragment with an ellipsoid grain, are revealed. On this basis, the calculated support for the design of nitride ceramic parts for operation under specific conditions is formed.

Keywords: nitride ceramics, surface layer, asymmetrical fragment, ellipsoidal grain, heat flux, thermo-elastic deformation, stress heterogeneity.
