  1. E0 and E90 are the longitudinal and transverse modulus of elasticity, respectively. G12 and G23 are the longitudinal and rolling shear modulus, respectively. Nu12 and Nu23 are Poisson’s ratios. ft,0 and ft,90 are tensile strength parallel and perpendicular to grain, respectively. fc,0 and fc,90 are compression strength parallel and perpendicular to grain, respectively. S0 is the shear strength parallel to grain
