## Homework Statement

I need to find thermal stresses that will be produced in a tank barrel as a result of firing. First of all, I want to know if theses stresses can be small enough to be neglected? And if not, then how can they be calculated? I basically know the solution but I want to be sure. If I can improve my solution in any way or if there can be another way to solve it, I would be interested.

I don't know the temperature after firing so I would be denoting it with T and initial temperature will be T

_{o}.

## Homework Equations

Thermal Stress= elastic modulus * coefficient of expansion * change in temperature

## The Attempt at a Solution

Using the

E=205 G Pa

coefficient of expansion = 15.69 x 10

^{-6}m/m.°C

change in temperature = T-T

_{o}

stress= 205*10

^{9}* 15.69 x 10

^{-6}* (T-T

_{o})
