With developments in rapid prototyping and novel methods for fringe plotting from finite element results, the technique is ideally suited for hybrid analysis of complex problems. ![]() It can be used to study models made of transparent plastics, prototypes made of different materials, and also directly on end products such as glass components. ![]() Photoelasticity is useful as a design tool, to understand complex phenomenological issues, and as an excellent teaching aid for stress analysis. The advancements in digital photoelasticity have made photoelastic analysis more efficient and reliable for solving engineering problems. It is the only whole-field technique which can study the interior of a three-dimensional model. The technique basically provides the difference of principal stresses/strains and their orientation at every point in the model domain. A representative fringe pattern for each of the variants is provided to give a glimpse of the range of problems it can solve. An overview of photoelasticity and its several variants ranging from conventional transmission photoelasticity to digital photoelasticity is presented.
