Strain Measurements by Full-Field Optical Techniques
A weak position and possibly leads to make a defected material and production. Localized strain concentration is becoming very important in the area of quality assurance. Recently, there are many research that researcher proposed using Computer-Aided-Engineering (CAE) tools to reduce the number of prototype builds and to speed up the development cycle. In this paper, there are some literature about researches that conducted in this field. The capabilities as well as the limitations for industrial applications are investigated. An application of this method is demonstrated on a stamping die to validate a FEM results. Full-field methods of strain measurements are very broad and many number of these techniques are using and can be widely categorized to two groups as Geometrical methods and Interferometric methods.
