Displacement is an important parameter in the assessment of integrity infrastructure; thus, its measurement required a multitude guidelines or codes for structural health monitoring most countries. To develop low-cost and remote displacement technique, novel method based on unmanned aerial vehicle (UAV) digital image correlation (DIC) presented this study. First, auxiliary reference that meets ...

Many applications in industry require non-contact, fast and accurate measurement of both surface profile and deformation field for manufacturing quality control and structural testing purposes. The fringe projection technique has been widely used due to its high accuracy and spatial resolution in measuring shape and out-of-plane displacement fields, but it cannot identify in-plane displacements...

The presented study focuses on measuring volume changes in elastomeric materials using digital image correlation (DIC), specifically the 2D DIC universal system and video-extensometer directly implemented to testing machine. Optical measurement methods were applied two-dimensional (2D) configurations during mechanical of dumbbell-shaped test specimens under uniaxial tension. measured data used ...

Finite element (FE) models of the spine are typically validated to be similar to the average experimental response of specimens with anatomical variation, such as varying sizes and degrees of degeneration. To account for this variation in a manner that allows validation against a specific vertebral response instead of an average range, specimen-specific models can be developed. The purpose of t...

Single-shot stereo 3D shape measurement is becoming more popular due to its advantages of noise robustness and short acquisition period. One of the key problems is stereo matching, which is related to the efficiency of background segmentation and seed point generation, etc. In this paper, a more efficient and automated matching algorithm based on digital image correlation (DIC) is proposed. The...

Digital Image Correlation (DIC) – also referred to as white light speckle technique – is an optical-numerical full-field measuring technique, which offers the possibility to determine in-plane displacement fields at the surface of objects under any kind of loading. For an optimal use of the method, the object of interest has to be covered with a speckle pattern. The present paper studies the ef...

Measuring displacement and strain fields at low observable scales of complex microstructures still remains a challenge in experimental mechanics often because the combination definition images with poor texture this scale. This is case for cellular materials, which local phenomena can occur. The aim paper to design validate numerically experimentally Digital Image Correlation (DIC) technique me...

We carried out a residual stress distribution analysis in a APS TBC throughout the depth of the coatings. The samples were heat treated at 1150 °C for 190 h and the data analysis used image based modelling based on the real 3D images measured by Computed Tomography (CT). The stress distribution in several 2D slices from the 3D model is included in this paper as well as the stress distribution a...

An experimental technique to accurately quantify the deformation and the bend-twist coupling of high performance composite foils under fluid loading is presented. The experimental results are reproduced in a Computational Fluid Dynamic (CFD) environment to assess the impact of board deflection and changes in pitch angle on vertical force generated in the C-foils while sailing under increased hy...
