A new hybrid method to obtain viscoelastic principal stress

  • Chen Yuhai


The basic relations in linear isotropic photoviscoelasticity have been theoretically discusse in details. A new routine has been found to obtain the time-dependent principal stress without the measurement of isoclinics. As a test of our method, examples are given at the end of this paper.
