摘要：

The paper presents research project focused on acoustic emission signals captured during commonly used static bending test of wood specimens. For five different wood types, typical AE patterns were identified in the acoustic emission records to further describe the under-the-stress behavior and failure development. Orthotropic properties of wood were found to be rather complicated to conform within known AE techniques. Evaluated properties of the material included MOE (modulus of elasticity), MOR (modulus of rapture), TTF (time to failure), and density. Results of the study will be included in a dissertation thesis focused on non-destructive diagnostics of wood using acoustic emission method.
