Abstract
The plates and beams made from the Oak, Beech, Pine, Spruce
and Birch have been loaded by the detonation of an explosive in contact. The
mechanical properties of these woods at dynamic loading have been evaluated by
the use of Hopkinson Split Pressure Bar Test and Charpy Impact test. The
minimum thickness of the wood at which no damage occurs has been evaluated.
These thickness are in a reasonable agreement with the mechanical properties
determined by the tests mentioned above. The same conclusion is valid for the
experiments on the explosive loading of wood beams. The results of the
preliminary numerical simulation of the used tests are also discussed. It seems
that the observed wood specimens behaviour may be explained in terms of the
Tsai - Wu strength model.
