Abstract
Moire methods are a versatile suite of techniques for deformation and strain measurement. In particular, it is one of the few methods that readily allow separate determination of the three displacement components. However, since the method still provides displacement components, novel approaches were used to get the derivatives of displacement, i.e strain components. There are two approaches that have been used for this - optical or digital. Optical methods provide high speed visual strain contours but digital methods can give quantitative information. This paper will look at some of the methods developed for strain derivation from moire fringes.
