Table 8 Reference strength properties expressed in terms of modulus of rupture (MOR); ultimate axial stress \(\sigma _{i,\tau }^u\) (\(i=R,T,L\)) in both traction (\(\tau =t\)) and compression (\(\tau =c\)); limit shear stresses in the three characteristic planes, i.e., LR, LT and RT, in terms of stress level at which the first crack onset occurs, i.e., \(\sigma _{\textrm{s,co}}\), of the ultimate shear stress, i.e., \(\sigma _{\textrm{s,u}}\), and of the shear strength, i.e., \(\sigma _{\textrm{s,s}}\) for Pinus Pinaster Ait. extracted from several studies
