Table 4: Dataset regarding density (kg/m 3 ), K IC (kPa · m ⁰⸱⁵ ), modulus of elasticity MOE(MPa) and Poisson’s ratio of the selected softwood. Tab. 4a refers to papers from 1 to 10; Tab 4b (density and K IC ) and Tab. 4c (MOE and Poisson’s ratio) refer to papers from 11 to 20. MC, RH and T written in the table are respectively moisture content (%), relative humidity (%) and temperature (°C). In Paper ID4, “ Sat .” is “saturated”; in Paper ID14 “ est. ” is “estimated value”. The acronyms are the same of those described in Tab. 3.
