The authors have developed a new automatic technique of drawing the master curve from the experimental data measured by the Dynamic Measurement Tester. In this paper, the experimental conditions recommended by Japanese Industrial Standards are considered and modified from the perspective of drawing the master curve. To verify the effectiveness of the proposed technique and the experimental conditions, the storage and loss moduli of epoxy resins and rubber materials are measured, and the proposed technique is applied to the experimental data. From the results, it is confirmed that the master curves are obtained automatically and expeditiously.

The authors propose a new method for simultaneous determination of both fringe order and principal direction of birefringence in practical photoviscoelastic analysis using a white incident light with a set of the three primary colors. When using this method, not only fringe order but principal birefringence direction are successfully and easily determined from a single color image through a plane polariscope. Utilizing this method together with photoviscoelastic constitutive equations, timedependent principal stress and strain difference, also their directions are obtained. In this paper, the fundamental of the tricolor photoviscoelastic technique is described briefly, then a successful application of the method to the analysis of an example of viscoelastic problem is shown.
