Photoelastic
WebPhotoelastic phenomenon can be best understood by a study of transmission photoelasticity. In this, usually plane or circularly polarized light is used to analyze a transparent model for stress information. Since polarized light is used, the basic equipment used is called a polariscope. WebDec 6, 2024 · The photoelastic method is an experimental technique that combines optics and mechanics for a stress analysis. The photoelastic phase-shifting technique is different from the moiré, holography, and speckle phase-shifting techniques, which only need to measure one parameter. The photoelastic phase-shifting technique needs to assess …
