Table 5: Geometry, load and displacement used for the determination of wood’s mechanical properties. The acquisition methods and the equations (shown in Appendix – section 2, A2) are referred to the investigation methodology through which the properties have been obtained. In this table: DCB = double cantilever beam; CT = compact tension specimen; WCT= wedge notched CT specimen; DR = displacement rate; LS = Loading speed; LR = loading rate.
