Overview
Thermal stress is mechanical stress created by any change in temperature of a material that is prevents from expanding or contracting. This can lead to deformation, cracking, or failure.

Pro Tips
Young's Modulus (E) for steel is ~200 GPa.
Linear expansion coefficient (α) for steel is ~12 x 10^-6 /°C.
Positive stress indicates compression (if heating) or tension (if cooling) depending on constraints.

Fun Facts
"Railway tracks can buckle if they get too hot and don't have enough room to expand."
"Glass can shatter if heated unevenly because the hot parts try to expand against the cold parts."
"Teeth can experience thermal stress when eating very hot food followed by very cold drinks."
