“…The first image corresponded to the unmodified fractured tibia-fibula complex (reference state) and the second 3D image corresponded to the maximal displacement of the fragments involved by ballon inflation during reduction. To reduce the amount of input data, a mask based on the segmentation of the separated fragment was created and imported in the software X-DVCorrel (Valle et al 2019).…”

“…More recently, a new local DIC approach, called Heaviside-DIC, has been developed. This approach considers kinematical discontinuities inside each subset during the correlation step of analysis, and has been applied and validated for 2D and 3D displacement fields [12][13][14]. The conventional DIC method only provides displacement results that are filtered and non-representative near discontinuities; this is due to the low-pass filtering effect of the classical kinematic representation.…”

“…The conventional DIC method only provides displacement results that are filtered and non-representative near discontinuities; this is due to the low-pass filtering effect of the classical kinematic representation. However, the Heaviside-DIC approach eliminates this shortcoming and extracts accurate displacement fields near discontinuities [12][13][14]. Its viability has been demonstrated for deformation of materials that involve discontinuities such as cracks [14], interfacial sliding [12], and slip bands [6].…”

The recent development of the high resolution and discontinuity-tolerant digital image correlation technique enables the extraction of discontinuities within a displacement field. The technique provides quantitative analysis of discontinuities arising from slip, shear bands, cracks, and grain boundary sliding in a variety of material systems, including polycrystalline metallic materials. The discontinuity-tolerant digital image correlation method can be implemented to retrieve not only quantitative discontinuity analysis but also the local strain and rotation fields that operate near these discontinuities. The present implementation includes high-resolution digital image correlation (HR-DIC) measurements collected in a scanning electron microscope for analysis of both the plastic and elastic fields that develop during deformation of polycrystalline metallic materials. The combination of the discontinuity-tolerant DIC technique with the computation of internal gradients enables extraction of non-localized strain and rotation fields during plastic deformation of a nickel-based superalloy. Therefore the lattice rotation/expansion and plastic localization that occur during deformation can be determined in a single experiment. This method is validated using synthetic images with preset deformation, and experimental measurements using the electron back scatter diffraction (EBSD) technique.

“…local or global). Today several algorithms to perform the DIC in order to evaluate the fracture parameters are proposed [29][30][31][32][33][34][35][36][37]. In the present study, the analysis was performed using Correla software's, developed by PEM team of Pprim Institut of Poitiers [38][39].…”

Particleboard (PB) are wood-based composites with fine wood fibers bound together by a small amount of polymeric adhesive, widely used in furniture industry and civil engineering. PB plates can be painted, laminated or veneered, and have good dimensional stability and load bearing capacity when properly designed. However, the deformation and fracture of such elements create malfunctions of structures made of MDF. This paper presents experimental results obtained for three point bending (TPB) tests, mode I and mode II fracture toughness. The bending tests were carried on rectangular specimens, while the fracture toughness tests were performed on Single Edge Notched Bend (SENB) specimens for mode I, respectively on Compact Shear (CS) specimens for mode II loadings. Digital Image Correlation technique allows the determination of the Crack Relative Displacement Factor and estimation of the Energy Release Rate.
