STRESS FREEZING DEVICE FOR PHOTOELASTIC TESTS

摘要

The present invention concerns a device capable of creating a stress state in a plastic test subject, wherein the isochromatic curves are viewed using a light source and two polarizing filters, by heating the same to a predetermined temperature and subsequently cooling the same, in such way that the stresses on the test subject are recorded thereon permanently. This invention, within the field of structural analysis, forms part of photoelasticity, and the design and development thereof are based on relevant know-how and research related with the elasticity and resistance of materials.
