1)(Stress–strain relationship for Neo–Hookean model) Plot the nominal stress–strain relationship for a Neo–Hookean model under uniaxial tension and compression and compare it with linear elastic material with the same modulus

1)(Stress–strain relationship for Neo–Hookean model) Plot the nominal stress–strain relationship for a Neo–Hookean model under uniaxial tension and compression and compare it with linear elastic material with the same modulus. Assume material parameter A₁₀=10MPa and incompressibility.

2)Relation between Mooney-Rivlin and Ogden models) Write the material parameters μ1 and μ2 in the Ogden model in terms of A10 and A01 in the Mooney-Rivlin model. Use N=2, α₁=2, and α₂=-2 for the Ogden model.
