The tests were carried out based on the Kolsky method using the split Hopkinson pressure bar. To study the anisotropy of properties, aspen samples were fabricated and tested by cutting along and across the fibers direction. Dynamic stress-strain curves were obtained as well as the average values of modulus of active loading sites. The greatest steepness of the loading branches and the highest breaking stresses are observed for the samples loaded along the fiber direction, while the smallest values are noted under loading across the fiber direction. Also the effect of elevated temperature on strength and deformation properties of aspen is estimated.}, keywords = {wood,aspen,strain diagrams,strain rate,Kolsky method}, url = {https://jacm.scu.ac.ir/article_17107.html}, eprint = {https://jacm.scu.ac.ir/article_17107_3e1761bd855de62200789423d2d26b62.pdf} }
