In this article, we demonstrate the application of digital image correlation (DIC) in evaluating strains and Poisson ratio a range soft materials terms their spatial temporal resolutions. Homogeneous samples polydimethylsiloxane (PDMS) elastomer were used as control substance measured to have ratios 0.498, 0.503, 0.500, 0.499, agreement with reported incompressible value 0.50. Two carbon nanotube (CNT) composites identical composition, but one homogeneous other highly inhomogeneous CNT...
Abstract The use of experimental tests that involve full‐field measurements to characterize mechanical material properties is becoming more widespread within the engineering community. In particular digital image correlation (DIC) on white light speckles one most used tools, thanks relatively low cost equipment and availability dedicated software. Nonetheless impact measurement errors identified parameters still not completely understood. To this purpose, in paper, a simulator able...
We present quasielastic neutrino-nucleus cross sections in the energy range from 150 MeV to 5 GeV for target nuclei $^{12}\mathrm{C}$ and $^{56}\mathrm{Fe}$. A relativistic description of nuclear dynamics coupling is adopted. For treatment final-state interactions we rely on two frameworks succesfully applied exclusive electron-nucleus scattering: a optical potential multiple-scattering Glauber approximation. At lower energies, optical-potential approach considered be optimum choice, whereas...
Abstract: A multi‐camera stereo digital image correlation (MC‐DIC) set‐up is presented to obtain full displacement and strain fields of a sheet‐metal specimen subjected an Erichsen test. The composed several conventional DIC systems (two camera set‐up), each which tracks the deformation aspect specimen. individual measurements, including geometries displacements, are then converted same reference frame integrate into global view. Afterwards, calculated based on field. It found that geometry...
Abstract: In this research, numerical 2D digital image correlation (DIC) tests are carried out to assess the uncertainty of DIC under heterogeneous strain states. is implemented measure deformation numerically deformed images with respect undeformed counterparts, which taken from real tensile specimens. The specimens made three materials, that is, steel DC06, DX54D+Z and aluminium alloy Al6016 cut into different geometries, namely one standard design two complex designs. all painted manually...
Abstract This paper presents a theoretical uncertainty quantification of displacement measurements by subset‐based 2D‐digital image correlation. A generalised solution to estimate the random error measurement is presented. The obtained suggests that determined noise, summation intensity gradient in subset, subpixel part displacement, and interpolation scheme. proposed method validated with virtual digital correlation tests.
Abstract Full‐field data from digital image correlation (DIC) provide rich information for finite‐element analysis (FEA) validation. However, there are several inherent inconsistencies between FEA and DIC that must be rectified before meaningful, quantitative comparisons can made, including strain formulations, coordinate systems, locations, calculation algorithms, spatial resolutions filtering. In this paper, we investigate two full‐field validation approaches: (1) the direct interpolation...
Abstract This article presents a methodology to optimise the design of realistic mechanical test characterise material elastic stiffness parameters an orthotropic PVC foam in one single test. Two main experimental techniques were used this study: Digital Image Correlation (DIC) and Virtual Fields Method (VFM). The actual image recording process was mimicked by numerically generating series deformed synthetic images. Subsequent this, entire measurement data processing procedure simulated...
Abstract Full‐field optical experimental techniques such as Digital Image Correlation (DIC) enable measurement of information‐rich heterogeneous strain states. The aim Material Testing 2.0 is to capitalise on this and design setups for efficient material characterisation using inverse identification the Virtual Fields Method (VFM). In that case, however, a priori knowledge constitutive model required, which sometimes not trivial task. This limitation can be overcome by identifying multiple...
