Photoelasticity: Principles, Methods and Applications to Materials Testing, Metallurgy and Mechanics, Parts I, II, III

摘要

The practical utility of photoelasticity was proved experimentally. The results obtained optically agree with the values found by other methods on metal pieces. Nevertheless, despite the service already rendered by photoelasticity, some persons are reluctant to use it, considering it a delicate, difficultly interpretable method, and, especially, an expensive method. The use of synthetic resins had considerably modified the method, while preserving its precision. With these resins the cost price of a model is insignificant.
