Abstract

The artificial birefringence behavior of visco-elasto-plastic polymers under stress generally exhibit creep effect. The author has often reported studies on creep and sign of birefringence. In those papers1-4, it was reported that positive and negative signs of birefringence depend on the temperature and the loading time. In this paper, the variational quantity of principal refractive index and the birefringence of polymers during the creep under a constant stress and a constant temperature were investigated in the temperature range from -100°C to 130°C using the Mach-Zehnder interferometer and photoelectric apparatus. The sign and components of artificial birefringence which depend on the temperature and the loading time were determined, and the birefringence behavior of polymers are classified into four types by combinations of the component signs. Moreover, the visco-elasto-plastic stress and strain in polymers were analyzed with relations among loading time, birefringence, stress and strain which were obtained by tensile creep testing for birefringence and strain of materials.
