Full-field data from digital image correlation (DIC) provide rich information for finite-element analysis (FEA) validation. However, there are several inherent inconsistencies between FEA and DIC data that must be rectified before meaningful, quantit

Recently, the issue of automatically defining virtual fields for non-linear constitutive models has been resolved (Marek et al., Comput Mech 60:409–431, 2017), relying on a new sensitivity-based approach hereby reducing the influence of noise on th

Stereo digital image correlation (stereo-DIC) is being accepted by the industry as a valid full-field measurement technique for measuring shape, motion and deformation, and it is therefore of utmost importance to provide uncertainties on the obtained

Thermo-graphic investigations were carried out on niobium microalloyed steel. During tensile testing temperature changes of samples, due to elastic and plastic deformation, were measured using infrared camera. The results of temperature measurements

In FE based global digital image correlation (DIC) a finite element mesh is used to describe the deformation of the region of interest (ROI). However, the identification of an optimal mesh is a difficult problem and is often obtained by using “mech

In this paper, the strain error of subset-based two-dimensional digital image correlation (DIC) is theoretically derived. Analytical solutions are provided to estimate the strain error. A dimensionless factor is proposed, namely the overlap magnifier
