Converting Youngs Modulus to C10
You commented that for small deformation(strain),Neo-Hookean model, it can be assumed that
E: Youngs Modulus
G: Shear Modulus
Can you please define the so called small deformation. e.g strain<15% or <100%? so that the equation above is valid?
If the deformation is large and the material manufacturer provided me only the Youngs modulus and Poissons ratio, is there anyway or formula i can apply to obtain the C[SIZE=1]10 [/SIZE][SIZE=2]coeeficient for NeoHookean model?[/SIZE]
You can still use that formula for large deformations, but if all you know are E and nu, then you really do not know the large-strain response and the Neo-Hookean model will be an approximation of the response.
