Description
| - The objective of the study was to perform a finite element (FE) simulation of elastic wave (EW) propagation in wood (Picea abies spp.). Based on measuring of tree rings width a FE model of wood with defined tree rings, substituted as an ideal annulus, was created. FE model was loaded to force impulse at different positions via the specimen length. Subsequently a propagation and travel timeof the EW through a material was observed. FE simulations were compared to the experimental ones acquired by different non-destructive acoustical tools (ADD, Geotron, FAKOPP and TICO). Results say that the FE model preserves trend of velocities of EW obtained from experiments, although comparing to them it embodies lower EW velocities in general. Relative difference of FE model towards experimental average is 20 %. Presented simulation of EW propagation can be supposed as a relatively accurate, but to achieve higher agreement with experiments, it needs to be optimized in terms of its material properties.
