要約

A universal model for predicting the thermophysical and thermomechanical properties of layered composites, designed for the conditions of intense and sharply varying thermal effects, was developed. The procedure of identification of the model parameters based on experimental data was formalized in mathematical terms and implemented. Mathematical problems of engineering and functional optimization of the structural parameters of the layered composite were formulated in order to reach the required set of the physicomechanical characteristics of the final material. The temperature distribution and the pattern of the stress-strain state in the structure of the Al2O3–Cr layered composite were modeled numerically in conditions of intense thermal effect. The developed model was verified by the results of experimental investigations performed on the prototype of the Al2O3–Cr layered composite.
