The stress wave propagation in the solid medium is affected by the change in temperature of the medium. In this paper, we observe the patterns of the propagating stress waves in the rod of rectangular cross section at high temperatures and room temperature by the photographic method, and analyze the dynamic behavior of stress waves by means of the high speed photoelastic experimental method with the aid of a semiconductor strain gauge in order to examine the effect of temperature on the velocity of the propagating stress waves in the isotropic medium. We consider the velocity of the propagating stress waves in the high temperature and room temperature media by using the thermodynamical method. The experimental results on the velocity of propagation of stress waves are found to be in fairly good agreement with the theoretical values of velocity derived from the thermodynamical consideration.
