Apparatus and method for measuring the strength and thermal shock behaviour of material samples

摘要

A sample (2) of ceramic film is used which has an axially symmetrical, curved shape. The film sample may be spherically curved, or cosinusoidally curved. A disc-shaped sample may be used that has a thickness for which there is an even state of stress up to the breaking point, without significant buckling caused by material tensions. An Independent claim is included for a method of measuring the strength of ceramic materials.
