A simplified optical method based on photoviscoelasticity is proposed for measuring the transient stress and strain generated in a two-dimensional photoviscoelastic body. First, the fundamental equation for the simplified optical method is derived from the relation ships between the stress, strain and birefringence in the two-dimensional photoviscoelastic body based on the linear photoviscoelastic theory. As an example of the application, transient stress, strain and birefringence produced by nonproportional loading under a constant temperature are measured by using the simplified optical method. Next, these stresses and strains under the same conditions are theoretically calculated based on the linear viscoelasticity. The effectiveness of the simplified optical method is assessed by comparing the results.
