5. Photoelasticimetry

Photoelasticity is one of the oldest photomechanical techniques. It was widely used in the 20th century to visualize the distribution of stresses in models, in order to design and optimize the shape of complex mechanical structures (aeronautics, automobiles, civil engineering). . Numerous experimental analysis techniques were then developed for both research and industrial needs. Since the advent of calculation codes, the use of photoelasticity for industrial design has become less predominant. At present, however, its main use is for validating calculation codes, as there is always a need to compare experimentation and modeling. This is aided by the development of 3D analysis tools and...
