METHOD FOR DESTROYING MATERIAL SOLID BODY UNDER LOCAL HIGHLY INTENSIVE HEAT IMPACT ON SURFACE THEREOF Russian patent published in 2021 - IPC B02C19/18 G01N3/54 G01N25/72 

FIELD: engineering.

SUBSTANCE: invention relates to the field of destruction of a material solid body (MSB) by at least two sources of local highly intensive heat impact (LHIHI), forming an impact area consisting of figures selected from a group: a ring, a frame, assuming that the maximum concentration coefficient of thermoelastic stresses attributed to the interference of elastic waves in this area is achieved, and is aimed at providing effective modes of LHIHI sources on the surface of the MSB for destruction thereof, including technical apparatuses (TA), by reducing the ultimate tensile strength of the material of the solid body or reducing the load-bearing capacity of the structure of technical apparatuses made of metals, alloys, composite materials, as well as optical and optoelectronic apparatuses. Thermoelastic (thermal) stresses are a type of mechanical stress caused in the MSB by a change in the temperature or the unevenness of distribution thereof. Thermoelastic (thermal) stresses occur in the MSB due to the limited possibility of thermal expansion (compression) from the surrounding parts of the body or from other bodies surrounding the body. Thermoelastic (thermal) stresses can cause destruction of the MSB, parts and structural elements of the TA. LHIHI is understood as the impact of a heat flow source only on a certain (limited) part of the surface of the MSB in the form of a heat spot of various shapes, figures, and sizes.

EFFECT: provided effective modes of LHIHI sources on the surface of the MSB for destruction thereof.
