Resumo
Among the various strain measurement techniques, photoelasticity is one of the oldest and, in turn, more versatile and powerful. In recent years, important contributions are being carried out, which are transforming this technique in a modern measurement tool: software is being developed to implement it easily and without a highly skilled operator, and standards have been developed for the calibration of equipments, which will allow express measurements with their corresponding uncertainties, making them valid, comparable and reproducible. Moreover, significant progresses are being made in the use of stereolithography for the manufacture of photoelastic models, as well as their use for three-dimensional analysis by tomographic photoelasticity. This article describes all these contributions in order to provide potential users the understanding of the different photoelastic techniques, the extent to which these are developed and commercially available and their application possibilities.
