Time‐resolved integrated digital image correlation [PDF]

International Journal for Numerical Methods in Engineering, 2015
SummaryThis paper discusses a method that provides the direct identification of constitutive model parameters by intimately integrating the finite element method (FEM) with digital image correlation (DIC), namely, directly connecting the experimentally obtained images for all time increments to the unknown material parameters. The problem is formulated

Microcontact printing on metallic surfaces for optical deformation measurements; pp. 184–188 [PDF]

Proceedings of the Estonian Academy of Sciences, 2017
The measurement of the properties and behaviour of material is of fundamental importance in modern engineering. In recent years a breakthrough method for measuring surface deformation has been represented by digital image correlation.

Study of image characteristics on digital image correlation error assessment [PDF]

, 2009
In this paper, errors related to digital image correlation (DIC) technique applied to measurements of displacements are estimated. This work is based on the generation of synthetic images representative of real speckle patterns.

Assessment of digital image correlation measurement errors: methodology and results [PDF]

, 2009
Optical full-field measurement methods such as Digital Image Correlation (DIC) are increasingly used in the field of experimental mechanics, but they still suffer from a lack of information about their metrological performances. To assess the performance

Optimal digital color image correlation

Optics and Lasers in Engineering, 2020
Abstract Within the context of Digital Image Correlation (DIC), the optimal treatment of color images is considered. The mathematical bses of a weighted 3-field image correlation are first introduced, which are relevant for RGB encoded images. In this framework, noise characterization methods are developed as noise properties dictate the best suited ...
