However, this preferred method presents a serious bottleneck in that finite elemental results are typically full field, yet the analyst must work out the best way to match the results to the pointwise measurements. This is normally done by calculating the average values of the desired quantity over a number of finite elements around the region of interest. It is therefore very hard to achieve good correlation with a high level of confidence. The use of digital image correlation, however, has provided the industry with a much better way of validating the results in that it yields full field measurements. This paper investigates the application of digital image correlation to biological soft tissue. Although it does not report on the finite element validation process, it highlights the challenges that can be encountered when applying the method to biological soft tissue with a special emphasis on producing speckle pattern.FulltextenPlanar stressesPorcine achillies tendonsDigital image correlation systemMeasurement of planar stresses in porcine achillies tendons using digital image correlation systemBook ChapterN/A
