Critical phase-transition temperature for freezing stress in thermo-sensitive photopolymers used for visualizing stress fields in solids
TL;DR: In this paper, a reflection polariscope system with a high-temperature loading chamber was designed to freeze and capture the stress fringes in the printed model, and the effects of continuous temperature rise and loading during the frozen stress tests on the stress birefringence of the thermo-sensitive photopolymers were investigated.
