Thermal stresses in a finite composite cylinder joined together at the ends.

Abstract

This paper deals with the steady thermal stresses in a finite composite circular cylinder, in which two finite circular cylinders of different materials are joined together at the ends, under uniform temperature distribution. The thermoelastic problem is formulated in terms of a thermoelastic displacement potential and two harmonic stress functions. Numerical calculations and measurements using resistance strain gages are carried out for the case of the composite cylinder which consists of stainless steel and carbon steel. The experimental results are compared with the theoretical ones.
