Created by Mahesh Shenoy. Size considerations can be made by changes in length area or volume and so there are coefficients derivable for linear area and volume expansions. The change in the units volume when temperature changes can be expressed as.
It is usually expressed as a fractional change in length or volume per unit temperature change.
The change in volume due to thermal expansion is D V vV D T where v is the coefficient of volume expansion and v 3a. Thermal stress is created when thermal expansion is constrained. We can just use the stuff we learnt in linear expansion and apply it over here. Created by Mahesh Shenoy.
