A new device for determining the mechanical properties of wood
Kloiber, Michal ; Drdácký, Miloš
The paper presents a novel concept of a diagnostic tool for "in-situ" assessment of the mechanical characteristics of wood in a prepared 12 mm hole. The device enables direct determination of conventional strength and modul of deformation in arbitrary depth along timber profile .The aim was to verify the measurement results of the new device with measurements on already tested devices according to european standards. Experimental tests show above all a very good correlation between conventional strength by means of the new device and standard samples strength in pressure along the fibers. This semi-destructive method causes a very gentle damage and can be used for the assessmen of historic timber structures.
