METHOD OF DETERMINING ULTIMATE TENSILE STRENGTH OF CERAMIC AND COMPOSITE MATERIALS DURING INDUCTION HEATING Russian patent published in 2020 - IPC G01N3/18 G01N25/72 G01N25/58 

FIELD: measurement technology.

SUBSTANCE: invention relates to methods of determining mechanical characteristics of structural materials taking into account conditions of their use. Method of determining ultimate tensile strength of ceramic and composite materials includes induction heating to a given temperature at rate of 10–100 °C by means of an intermediate heating element and determination of ultimate tensile strength of the sample. Heating of the sample is carried out by an intermediate heating element from a high-melting conducting material heated by an induction heater to temperature of 1,300–1,700 °C.

EFFECT: high accuracy of determining tensile strength of ceramic and composite materials by approximating test conditions of the sample to operational thermal loads of material in the article.
