摘要

The device comprises equipment creating a freezing state in plastic test tube. The device comprises a focus light, two filters and a polarizer, where the test tube is heated to specific temperature and then cools down, and freezing state is recorded in permanent manner. The structural analysis related to photo elastic elasticity and resistance is done.
