Abstract

In this paper, the photoviscoelasticity method of viscoelastic stress analysis has been discussed in detail. It is shown that in order to avoid the effects of shrinkage and aging in the test specimens, it is suggested that the specimens should be tempered for three days at a temperature of 60°C before starting the experiments, and the temperature filtering arrangement is recommended in the experimental setups to keep the temperature absolutely constant. Besides the axi-symmetrical time-dependent stress state, the determination of the principle axes of the refraction tensor experimentally remains and unsufficiently solved problem. To avoid dynamic effect in the step wise loading, the time of measurement in every step should be limited in about one secend.
