Dynamic properties of some wood species

The report presents the dynamic test results for wood. Compression tests were done according to Kolsky method, using a 20-mm dia split Hopkinson pressure bar (SHPB). The samples were loaded both along and across the fibers. Obtained are dynamic deformation diagrams for pine, birch and lime. Direction of cutting is noted to affect the mechanical properties of the woods tested. The obtained deformation diagrams are nonlinear and differ in their loading and unloading brunches. For the wood species tested, the stress values resulting in different forms of fracture, such as cracking and spallation, were obtained Alongside with the SHPB tests, plane-wave experiments were conducted and shock adiabates for the wood samples were obtained.
