“…The study showed that a DVC approach implementing a continuity constraint between neighbouring subsets provided a higher strain accuracy and precision than local DVC approaches when evaluated using repeated scans without repositioning, in agreement with [23]. Another important aspect that should be addressed is the optimal image resolution for DVC, i.e., what image resolution is good enough to achieve a high correlation between the subsets while not having an unnecessarily high X-ray dose or long scanning time.…”

“…When compared to DIC with digital images, the use of X-ray tomographic reconstructions to calculate the strain field leads to two additional sources of noise, namely: (i) the noise of the tomographic images, which is generally higher than that of digital images, and (ii) that it is impossible to apply an artificial speckle pattern to enhance the correlation. The majority of studies adopting DVC on bone samples [16], [23], [51], investigated bone mechanical properties at the tissue-level. This is because the trabecular bone at the tissue-level consists of a spongy network which is very well suitable for the calculation of a correlation coefficient between subsets of such network.…”

“…Earlier reviews are either outdated and does therefore not include the latest developments [19]- [22], or limited to one single strain measurement technique [23]. Our aim is to provide a comprehensive review of the most commonly adopted methods to measure strains on bone, at a length scale of the organ-and tissue-level.…”

Osteoporosis related fractures are a social burden that advocates for more accurate fracture prediction methods. Mechanistic methods, e.g. finite element models, have been proposed as a tool to better predict bone mechanical behaviour and strength. However, there is little consensus about the optimal constitutive law to describe bone as a material. Extracting reliable and relevant strain data from experimental tests is of fundamental importance to better understand bone mechanical properties, and to validate numerical models.Several techniques have been used to measure strain in experimental mechanics, with substantial differences in terms of accuracy, precision, time-and length-scale. Each technique presents upsides and downsides that must be carefully evaluated when designing the experiment. Moreover, additional complexities are often encountered when applying such strain measurement techniques to bone, due to its complex composite structure. 2This review of literature examined the four most commonly adopted methods for strain measurements (strain gauges, fibre Bragg grating sensors, digital image correlation, and digital volume correlation), with a focus on studies with bone as a substrate material, at the organ and tissue level. For each of them the working principles, a summary of the main applications to bone mechanics at the organ-and tissue-level, and a list of pros and cons are provided.

“…The precision of the measured displacement and strains with a number of DVC approaches is reported by a number of studies. Conversely, the accuracy is only reported by a few of them (please see the exhaustive literature review by Roberts et al (2014) and the paper published recently by Gillard et al (2014)). The different DVC methods applied to trabecular bone led to wide ranges of accuracy and precision for displacement measurements: 0.004-0.272 voxels and 0.005-0.115 voxels (Liu and Morgan, 2007;Zauel et al, 2006), respectively.…”

The accurate measurement of local strain is necessary to study bone mechanics and to validate micro computed tomography (µCT) based finite element (FE) models at the tissue scale. Digital volume correlation (DVC) has been used to provide a volumetric estimation of local strain in trabecular bone sample with a reasonable accuracy. However, nothing has been reported so far for µCT based analysis of cortical bone. The goal of this study was to evaluate accuracy and precision of a deformable registration method for prediction of local zero-strains in bovine cortical and trabecular bone samples.The accuracy and precision were analyzed by comparing scans virtually displaced, repeated scans without any repositioning of the sample in the scanner and repeated scans with repositioning of the samples.The analysis showed that both precision and accuracy errors decrease with increasing the size of the region analyzed, by following power laws. The main source of error was found to be the intrinsic noise of the images compared to the others investigated. The results, once extrapolated for larger regions of interest that are typically used in the literature, were in most cases better than the ones previously reported. For a nodal spacing equal to 50 voxels (498 µm), the accuracy and precision ranges were 425-692 µ and 202-394µ , respectively. In conclusion, it was shown that the proposed method can be used to study the local deformation of cortical and trabecular bone loaded beyond yield, if a sufficiently high nodal spacing is used.3

Biomineralized materials are sophisticated material systems with hierarchical 3D material architectures, which are broadly used as model systems for fundamental mechanical, materials science, and biomimetic studies. The current knowledge of the structure of biological materials is mainly based on 2D imaging, which often impedes comprehensive and accurate understanding of the materials’ intricate 3D microstructure and consequently their mechanics, functions, and bioinspired designs. The development of 3D techniques such as tomography, additive manufacturing, and 4D testing has opened pathways to study biological materials fully in 3D. This review discusses how applying 3D techniques can provide new insights into biomineralized materials that are either well known or possess complex microstructures that are challenging to understand in the 2D framework. The diverse structures of biomineralized materials are characterized based on four universal structural motifs. Nacre is selected as an example to demonstrate how the progression of knowledge from 2D to 3D can bring substantial improvements to understanding the growth mechanism, biomechanics, and bioinspired designs. State‐of‐the‐art multiscale 3D tomographic techniques are discussed with a focus on their integration with 3D geometric quantification, 4D in situ experiments, and multiscale modeling. Outlook is given on the emerging approaches to investigate the synthesis–structure–function–biomimetics relationship.
