Heterogeneity of density of green beech wood caused by fungal deterioration and its impact on mechanical testing
Original language description
This study investigates the effect of wood degradation and its heterogeneity caused by the wood-decaying fungus Kretzschmaria deusta on mechanical (elastic bending modulus of elasticity (M0Et) and modulus of rupture (MOR)) and vibro-acoustic parameters (dynamic elastic modulus (M0EDt) and longitudinal stresswave velocity (Q)) of green beech wood specimens. According to the results, degraded samples have a statistically proved higher variability of density distribution than reference intact specimens. The application of paraffine wax on the specimens' faces didn't attenuate the heterogenic distribution of density among the samples' length. A relevant correlation between density variability and MOR was proven. M0EDt has a stronger linear relationship to MOR than c(. Presented results can be in future applied to obtain more reliable results of non-destructive methods used for wood decay identification in wood.
