THERMAL AND STRESSED STATES OF A TUBE
IN TRANSPORTATION OF LIQUID SODIUM

UDC 539.3

Using the method of "superelements," the thermoelasticity 
problem is solved for a hollow cylinder with liquid sodium flowing 
inside the cylinder. The problem for each superelement is reduced 
to a system of difference equations solvable by the iteration method. 
The influence of the swelling of the crystal lattice of steel on the 
stressed-strained state is taken into account in the case where carbon 
penetrates into the lattice.
