Srovnání rychlosti akustického signálu s mechanickými vlastnostmi dřeva javoru

Work is processed by comparing the propagation velocity of the acoustic signal in the maple and hornbeam. Another object of this work was to determine the dependent propagation speed of the acoustic signal in comparison with the mechanical properties of maple wood. Meaurement the speed of the acoustic signal was measured acoustic tomography Fakopp ArborSonic and 3D mechanical properties were measured in a universal testing machine ZWICK Of the 050 samples were used from one maple and hornbeam one that grew in urban environments
