Název v původním jazyce

Heterogeneity of density of green beech wood caused by fungal deterioration and its impact on mechanical testing

Popis výsledku v původním jazyce

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&apos; faces didn&apos;t attenuate the heterogenic distribution of density among the samples&apos; 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.
