Optical methods in experimental stress analysis, such as photoelasticity, moire interferometry, speckle interferometry and holographic interferometry, are very valuable in areas where other methods of analysis are not available or impractical. Though optical methods have many advantages, these optical methods are not so widely used. One of these reasons is that currently there are no standards which cover procedures, materials and equipments for any of optical methods. In order to standardize the optical methods in stress and strain analysis, TWA26 in VAMAS is in active and the standardization of full-field optical stress and strain measurement division has been established in JSEM. The present paper describes the current activities of the standardization of full-field optical methods in VAMAS TWA26, ASTM and JSEM.
