Abstract (en)

[origin: WO2009040168A1] The invention relates to a method for determining the thermal shock robustness and material strength of brittle failure, in particular ceramic, materials, wherein this method comprises the following steps: (a) at least one material sample is homogeneously heated to a desired temperature, (b) a local thermal shock is induced by cooling using a fluid whose form and volume are defined, wherein the fluid has a Weber number of We = 130, (c) the material sample is tested for cracking, (d) steps a) to c) are optionally repeated with the material sample, wherein a higher desired temperature level is set in step a). The invention also relates to an apparatus for carrying out the method.
