Thermal shock-Relative robustness of materials

The robustness of a material to thermal shock, or thermal shock resistance^[2] is characterized with the thermal shock parameter:^[3]

where

• {\displaystyle k} is thermal conductivity,

• {\displaystyle \sigma _{\mathrm {T} }} is maximal tension the material can resist,

• {\displaystyle \alpha } is the thermal expansion coefficient

• {\displaystyle E} is the Young's modulus, and

• {\displaystyle \nu } is the Poisson ratio.
