The investigation described here was undertaken in an attempt to examine the reliability of high temperature strain gauges in the experimental thermal strain measurements. A long, thick-wall hollow cylinder, with uniform inner heating and an adiabatic outside wall, was taken as the test specimen, because of the simplicity in establishing the analytical boundary conditions in the experiment and also the simplicity in comparing the experimental thermal strains with the analytical ones. The transient thermal strains in the axial and the circumferential directions on the outer surface of the cylinder were measured by using one strain gauge for each direction. These strain gauges are called to be able to measure strains up to 315C. The experimental results obtained correspond closely to the analytical results obtained in the tendencies of change and the magnitude of change. Thus, it can be expected that reliable experimental thermal strains can be measured with high temperature strain gauges.
