TLDR
In this paper, a comprehensive overview of image correlation for shape, motion and deformation measurements is provided. But, the authors do not discuss the effect of out-of-plane motion on 2D measurements.Abstract:
Image Correlation for Shape, Motion and Deformation Measurements provides a comprehensive overview of data extraction through image analysis. Readers will find and in-depth look into various single- and multi-camera models (2D-DIC and 3D-DIC), two- and three-dimensional computer vision, and volumetric digital image correlation (VDIC). Fundamentals of accurate image matching are described, along with presentations of both new methods for quantitative error estimates in correlation-based motion measurements, and the effect of out-of-plane motion on 2D measurements. Thorough appendices offer descriptions of continuum mechanics formulations, methods for local surface strain estimation and non-linear optimization, as well as terminology in statistics and probability. With equal treatment of computer vision fundamentals and techniques for practical applications, this volume is both a reference for academic and industry-based researchers and engineers, as well as a valuable companion text for appropriate vision-based educational offerings.read more

An experimental study of the behaviour of delaminations in composite panels subjected to bending
TL;DR: In this paper, the effect of delamination size and shape on buckling behavior was investigated using circular and elliptical delaminations in thin beams under four-point bending, and the results showed that the orientation of the delamination had a small influence on the critical delamination-buckling load, which decreased with increasing ratio of minor to major axis length.

Direct Evaluation of Cohesive Law in Mode I of Pinus pinaster by Digital Image Correlation
TL;DR: In this paper, the authors proposed a data reduction scheme for assessing the cohesive law in pure mode I of Pinus pinaster, which relies on the concept of equivalent elastic crack length (a eq) and does not require the monitoring of crack propagation during test.

Identifiability of material parameters in solid mechanics
TL;DR: In this paper, the authors investigate some very basic single and two-layered examples regarding identifiability, because these tests are the basis for more complex geometrical and physical nonlinear problems.
