Using DIC in measurement of strains induced in trees during bending
Original language description
Assessment of mechanical behavior and safety of trees have been paid a big attention in recent years in both ways research and practical. The research - tree biomechanics - mostly focuses on evaluation of tree mechanical response that is dependent on a root-soil interaction and also on wood propeties. The goal of the study was to measure and investigate an influence of a bark of Turkish hazel (Corylus colurna L.) on strain transfer from xylem to bark surface. The study addresses issues of tree biomechanics that calls for a high quality deformation data measured on trees' surfaces in a non-invasive way. For these purposes, the optical technique employing 3D digital image correlation (3D-DIC) was used and tested against extensometers commonly used for such applications. Measured tree was subjected to a bending by a two pulling tests to induce the strain in tree stem during which the analyzed area of interest (AOI) on the tree was studied in both variants with bark and without.
