This work focuses on the comparison of the
strain energy density functions for rubber-like materials
based on exponential form. The Treloar experimental
data had been used in the present paper. The optimal
method for nonlinear parameter identification is
developed. Indeed, a comparison between the Treloar
data and the analytical solution is approached in order
to identify a good hyperelastic parameters of the models.
By processing simple tension, pure shear and equibiaxial
tension curves showed the good agreement between the
model and experimental data.
