METHOD FOR DETERMINING THE TENSILE MODULUS OF CERAMIC AND COMPOSITE MATERIALS DURING INDUCTION HEATING Russian patent published in 2023 - IPC G01N3/18 

FIELD: structural materials characteristics determination.

SUBSTANCE: invention relates to methods for determining the deformation (mechanical) characteristics of structural materials, taking into account the conditions of their use. The sample is heated at a heating rate of 10-100°C/s to a predetermined temperature by means of an intermediate heating element made of a refractory electrically conductive material installed near the sample and heated by an induction heater, the sample is stretched and its deformation is measured with a non-contact laser extensometer, the dimensions of the working zone of which coincide with the dimensions heating zone, the value of which determines the modulus of elasticity of the material.

EFFECT: improving the accuracy of determining the tensile modulus of ceramic and composite materials by bringing the test conditions of products closer to operational thermal loads.
