Dataset supporting publication: "Experimental Characterization of a Smart Material via DIC"
<p>Dataset supporting publication: “Experimental Characterization of a Smart Material via DIC” (publication available in <a href="https://zenodo.org/record/7266424#.Y1_dynbMJPY">GEOFIT Zenodo</a>)</p> <p>Datasets resultant from structural health monitoring activities (accelerometer data).</p> <p>When no extensometer is available in a generic tensile-compression test carried out by a universal testing machine (for instance the model BIONIX from Material Testing Systems (MTS), the test results only provide the relative displacement between the machine grips. The test does not provide any information on the local behaviour of the material. This contribution presents the potential of an application of Digital Image Correlation (DIC) toward the reconstruction of the behaviour along the specimen. In particular, the authors test a Ni-Ti shape memory alloys (SMA) specimen with emphasis on the coupling of the two measurement techniques. The activity reported in this work have been founded by European Union Horizon 2020 research and innovation program under grant agreement No 792210 (GEOFIT).</p>

DIC performance for huge strains: The X-Strain DIC Challenge (GeM/ECN batch images)
<p>There are in this repository <strong>2 sets of images </strong>of flat elastomeric membranes that are severely deformed (up to several hundred % deformation). A speckle and dots have been deposited on the membranes in order to perform image analysis and measure the deformation fields. The document ’<em>Large_strain_images.pdf’</em> explains how the images were obtained. These images can be used as a benchmark for digital image correlation codes in case of very large deformations (i.e. The X-Strain DIC Challenge, <a href="http://sem.org/dicchallenge">https://sem.org/dicchallenge</a>).</p> <ul> <li>First set of images : 360 bmp images of size 38.8 Mo (<a href="https://zenodo.org/api/files/dbac452a-e701-4b5d-b05c-edafa7e442c8/20190926.zip">20190926.zip</a>)</li> <li>Second set of images : 820 bmp images of size 32.5 Mo (<a href="https://zenodo.org/api/files/dbac452a-e701-4b5d-b05c-edafa7e442c8/20191220.zip">20191220.zip</a>) </li> <li>Technical data sheet of the materials (<a href="https://zenodo.org/api/files/dbac452a-e701-4b5d-b05c-edafa7e442c8/Data_sheet.zip">Data_sheet.zip</a>)</li> <li>A technical report on how the images where obtained (<a href="https://zenodo.org/api/files/dbac452a-e701-4b5d-b05c-edafa7e442c8/Large_strain_Images.pdf">Large_strain_Images.pdf</a>)</li> </ul>

Experimental dataset: stereo-DIC experiment on uniaxially loaded, S-Shaped, high density polyethylene test sample
<p>Stereo-DIC experiments were performed on uniaxially loaded, s-shaped, high-density polyethylene test sample. 100 stationary images of unloaded test sample were taken for evaluation of DIC noise floor. Stereo calibration image dataset, involving a calibration target with rectangular grid (12 by 9 and pitch of 10 mm), is also made available. Tensile load from the test bench load-cell sampled at each moment an image is captured is available. </p>

DIC Images and Data of In-Plane Cyclic Testing of a 3D-Woven Layer-to-Layer Angle Interlock Composite
<p>Data behind the publications:</p> <ul> <li>C. Oddy, M. Song, C. Stewart, B. El Said, M. Ekh, S. Hallett and Martin Fagerström: On and Off-Axis Cyclic Behaviour of 3D-Woven Composites: Experimental Testing and Macroscale Modelling. Submitted for international publication.</li> </ul> <p>For each test sample orientation and excel file is provided. This includes the machinedata giving the time, machine displacement and force. On another sheet, informationfrom the DIC analysis is given, including the time and force signal organised accordingto the image frame number. The DIC images are also provided.</p> <p>The testing was carried out using a serial camera DIC system. However, as part of this publication, the images have only been provided from one of the camera systems. They have also been exported at a lower image quality than the original analysis. The authors' can recommend the use of open source DIC software, for example DICe (https://github.com/dicengine/dice), to carry out any type of further image processing. Processing the stereo image as a 2D analysis at a lower image quality may lead to some deviations in the extracted strain or displacement fields. The authors however have compared the results and have not seen any notable inconsistencies. We hope that these images can be useful to you in your own research endeavours! </p> <p> </p>
