Full-field representation of discretely sampled surface deformation for displacement and strain analysis

Fracture and damage mechanics modelling of thin-walled structures – An overview

“…The CTOA is than the angle enclosed by the upper and lower lines, L 1 and L 2 . A special case of optical measurement is the digital image correlation method [39,[41][42]. In [43] the authors, following earlier attempts, use a digital camera technique for investigating relatively tough pipeline materials.…”

In-plane strain measurement by digital image correlation

“…In the last decade, a non-contacting optical technique, digital image correlation, has been developed by Sutton et al (1983Sutton et al ( , 1986Sutton et al ( , 1988Sutton et al ( , 1991 and Bruck, et al (1989). It was applied to measurement of displacements and strains.…”

Optical Techniques for Defect Evaluation in Vehicles

“…Digital image correlation belongs to the class of non-contacting measurement methods that were developed by Sutton (Sutton M. A. et al, 1983;Sutton M. A. et al, 1986;Sutton M. A. et al, 1991;Sutton M. A. et al, 1988) and by Bruck (Bruck A. et al, 1989), in which acquires images of an object, store these images in digital form and perform image analysis to obtain full-field shape, deformation and motion measurements (Sutton M. A. et al, 2009). In this method is used a mathematical correlation to estimate the displacement in the plane surfaces or structures of components subject to mechanical or thermal stresses.…”
