This paper describes a quantitative method of stress relaxation measurement in prismatic glass samples during two different
time-temperature regimes using the Sénarmont compensator. Four types of glass (Barium crystal glass, Eutal, Simax, and
Container glass) were subjected to observation in an assembled measuring device. Results will be used for parameterization
of the Tool-Narayanaswamy-Mazurin model and consequently implemented in a finite element method code. |
