Relative Robustness of Materials
The robustness of a material to thermal shock is characterized with the thermal shock parameter:
- ,
where
- is thermal conductivity,
- is maximal tension the material can resist,
- is the thermal expansion coefficient
- is the Young's modulus, and
- is the Poisson ratio.

Famous quotes containing the words relative and/or materials:
“Personal change, growth, development, identity formationthese tasks that once were thought to belong to childhood and adolescence alone now are recognized as part of adult life as well. Gone is the belief that adulthood is, or ought to be, a time of internal peace and comfort, that growing pains belong only to the young; gone the belief that these are marker eventsa job, a mate, a childthrough which we will pass into a life of relative ease.”
—Lillian Breslow Rubin (20th century)
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
