Abstract

For most infrared—transmitting materials the primary cause of failure in a ri5si1e window/dome application can be attributed to brittle fracture induced by tensile stresses originating from instantaneous terperature gradients generated by aerodynamic heating. To describe the thermal shock I rely on the well known expression for the maximum stress experienced by a clamped plate (or a complete sphere), if there is a linear temperature variation across the thickness and both surfaces are free to expand:
