Using optical full-field measurement based on digital image correlation to measure strain on a tree subjected to mechanical load

Original language description

The goal of this study was to analyze and measure the displacement and strain response behavior of the tree (Juglans regia L.) subjected to a mechanical load. The analysis addresses issues of tree biomechanics that call for a high-quality deformation data measured on trees' surfaces in a noninvasive way. For these purposes, the 3D digital image correlation (3D-DIC) was proposed and tested against standard extensometers. The measured tree was subjected to a bending by a pulling test to induce strain on the tree stem. The DIC technique successfully provided strain field on a tree bark despite its highly complicated geometry. Vertical averaging of the strain field obtained by the DIC revealed that a tree stem behaves according to beam theory exhibiting compression and tension parts. The absolute values of strain measured by both techniques agree with each other in order of magnitude, DIC returning lower values (approximately 21.1 and 40.8 % for compression and tension part, respectively).
