Equation 17.9, for the thermal shock resistance of a material, is valid for relatively low rates of heat transfer.
When the rate is high, then, upon cooling of a body, the maximum temperature change allowable without thermal shock, ΔT_{f} , is approximately
where σ_{f} is the fracture strength. Using the data in Tables B.2, B.4, and B.6 (Appendix B)
Table B.2 Room-Temperature Modulus of Elasticity Values for Various Engineering Materials
Table B.4 Typical Room-Temperature Yield Strength, Tensile Strength, and Ductility (Percent Elongation) Values for Various Engineering Materials
Table B.6 Room-Temperature Linear Coefficient of Thermal Expansion Values for Various Engineering Materials
Determine ΔT_{f} for a soda–lime glass, borosilicate (Pyrex) glass, aluminum oxide (96% pure), and gallium arsenide [<100> direction and {100} orientation, as-cut surface].
