Thermal Stress

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Thermal stress, abbreviated as \( \sigma \) (Greek symbol sigma), is resulting from non uniform distribution of temperature.

 

thermal Stress formula

\(\large{ \sigma = \alpha \; E \; \Delta T   }\)   

Where:

\(\large{ \sigma }\)  (Greek symbol sigma) = thermal stress

\(\large{ E }\) = elastic modulus

\(\large{ \Delta T }\) = temperature differential

\(\large{ \alpha }\)  (Greek symbol alpha) = thermal expansion coefficient
