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

TL;DR: In this article, fly ash was used as an amorphous additive and the additional aluminum source to adjust the Si:Al ratio for better geopolymerization effects, and the Brazilian indirect tensile tests were conducted to evaluate the influence of different fly ash additions, 5, 10, 15, and 20%, on the tensile strength of the geopolymers.

Subsurface damage detection and structural health monitoring using digital image correlation and topology optimization
TL;DR: Results from this study have demonstrated that the proposed method is able to successfully extract detailed internal damage information that is otherwise expensive and difficult to achieve with state-of-the-art methods and can therefore be used as a promising subsurface damage detection method.

Grain Boundary Sliding and Slip Transmission in High Purity Aluminum
TL;DR: In this paper, the activity of grain boundary sliding (GBS) and the relationship between GBS and slip transmission at grain boundaries was investigated by the characterization of full-field strain and microstructural information in an experimental system of high-purity (99.99%) columnar aluminum subjected to uniaxial tension at 190°C.
