Table 2.

Fitted coefficients for the ANISO_G model, data represent mean (SD) values. C10, C20, k1 and k3 are in MPa, β and γ are in degrees and k2,k4,κ1 and κ2 are dimensionless. ∥, * and # indicate statistical significance. Specifically, these significance values compare the stiffness (k1, k3), nonlinear response (k2, k4), and the mean fiber orientation (β,γ) associated with the two fiber families of the ANUSO_G model.
