С использованием базовых положений компьютерной инженерии изучено напряженное состояние поверхностного слоя шлифованной Si3N4‒TiC-керамики под действием силовой нагрузки. Выявлено формирование микроструктурных концентраторов напряжений в точке приложения сосредоточенной силы, приводящих к изменению структуры керамики за счет образования несплошностей.

Regularities of stress-strain state of surface layer of Al2O3‒TiC-ceramics with AlN and TiN coatings under the action of force load are established using the methodology of computer engineering. The features of influence of AlN and TiN coatings on the nature of changes in the stress intensity in the surfaces of structural elements forming the surface layer of Al2O3‒TiC ceramics are determined. The formation of microstructural stress concentrators at the boundary of the AlN and TiN coatings with the initial ceramics is revealed.

A microstructural model of surface layer of machine elements from a nonuniform material is developed. With using of this model a calculation scheme that includes basic structural elements is created. Each element is characterized by the following properties: density, elastic modulus, thermal conductivity, linear expansion coefficient and Poisson's ratio. A mathematical model of surface layer of machine elements from a sintered nonuniform material is formulated on the basis of solution of two-dimensional heat-conduction and elasticity problems by the finite-element method. The created algorithms for solution of these problems are used for formation of an automated system for thermal strength calculations. This system is surrounded with some original techniques which provide the investigation of the stress-strain state of surface layer of machine elements from a sintered nonuniform material.

С использованием базовых положений компьютерной инженерии изучено тепловое и напряженное состояние поверхностного слоя шлифованной Si3N4‒TiC-керамики четырех систем под действием теплового потока. Установлены закономерности распределения температур и напряжений в шести выделенных поверхностях поверхностного слоя. Определена специфика формирования структурной неоднородности напряжений и микроструктурных концентраторов напряжений, приводящих к изменению структуры керамики за счет образования несплошностей.
