Studying the influence of defect on the dynamic behavior of wood in order to detect the local heterogeneities is of great importance in non-destructive testing of wood. The natural heterogeneities in wood are oriented in a volume. However, one- dimensional models are still used in dynamic characterization of wooden beams. The aim of this study was to experimentally investigate the effects of ...
