I have a tube, inside the vacuum (a few millibars) and a thermal power. Outside, air and convexion.
I would like to know, as a function of time, the internal stresses of the material due to the thermal power and the temperature gradient on the internal and external walls.
I would like to be helped or guided on how to know the internal stresses of the material due to the thermal power and the temperature gradient on the internal and external walls.
I would like to know, as a function of time, the internal constraints of the material due to the thermal power and the temperature gradient on the internal and external walls.
