Determination of brittleness of refractories tested for heat resistance
When determining heat resistance, it is advisable to classify materials not by their chemical composition, technology of manufacture, regions of application, or other such features, but by their behavior (deformation and fracture) during force loading.
For evaluating the behavior of materials during force loading we have proposed the ratio of potential energy accumulated in the specimen at the instant of fracture to the total energy expended on deformation of the specimen prior to its fracture.
