dr. Binienda and his lies part II


Zhang et al. (2013)/Math. Comput. For. Nat.-Res. Sci.Vol. 5, Issue 1, pp. 71{85/http://mcfns.com

page 75 Table 3: Material parameters for orthotropic elastic wood model
Young's Modulus (MPa) Poisson's Ratio Shear Modulus (MPa) Density (kg/m3)
EL ER ET LT RL RT GTL GLR GRT
10300 803.4 515 0.451 0.043 0.697 700.4 762.2 175.1 700

the last number is 30% underestimate, proper for dry birch logs, however a growing tree has the density of 900 kg/m3 ....

Even if Chao Zhang thought the tree (dead, broken or for whatever reason) was dry he should have used the a set of values for his analysis. Using a value which deviates from officially known facts is a manipulation unworthy of a scientist.
