Degradation of beech wood by Kretzschmaria deusta: its heterogeneity and influence on dynamic and static bending properties

Original language description

Strength loss caused by fungal degradation is an important factor to be considered during tree-stability assessment. Detailed information on the relationship between static mechanical properties in relation to the heterogeneity of density and dynamic mechanical parameters of wood degraded by the soft-rot fungus Kretzschmaria deusta can improve the understanding of its decay process and the interpretation of results obtained from stress-wave-based non-destructive methods used for tree-stability assessment. This research presents density profiles of artificially inoculated samples with K. deusta and static mechanical properties of green beech wood in relation to physical parameters (density, moisture content, vibroacoustic parameters). A statistically relevant difference (p &lt; 0.01) in the variability of density distribution between degraded and intact samples was proved. Relevant correlations were proved among modulus of rupture ( MOR ), mass loss and variability longitudinal density distribution. A strong linear relationship between MOR and static modulus of elasticity ( MOE ) of degraded and intact specimens was presented. A strong relationship was also proved between MOR and dynamic parameters (dynamic modulus of elasticity ( MOED ) and stress-wave velocity in longitudinal direction ( cl )). MOED showed a stronger correlation to MOR than cl proving the importance of density in assessing strength loss through non-destructive methods.
