THE MECHANICAL AND OPTICAL CHARACTERIZATION OF HYSOL 8705 WITH APPLICATION TO PHOTOVISCOELASTIC ANALYSIS,
Abstract
The main requirement for practical photoviscoelastic analysis is optical and mechanical characterization of the material. Time-dependent characteristics of a typical low modulus polymer material, Hysol 8705, are determined from constant strain rate tests for a full range of dynamic loading rates by taking advantage of the time-temperature shift phenomenon. The theory of linear viscoelasticity is then used to construct master curve representations for all pertinent properties of Hysol 8705. A one-dimensional photoviscoelastic experimental program was conducted to generate experimental data for comparison to a corresponding theoretical problem. A comparison is made between the analytically predicted fringe patterns and the experimental results; also, available two-dimensional considerations are examined. The results indicate the feasibility of quantitative photoviscoelasticity with engineering accuracy. (Author)
