Linear strain limit
Dear all,
One of the consistency conditions of
the Ogden model is that sum(μ)= initial classic shear modulus. To
apply this condition, I need to calculate slope of stress-strain
curve (of an experimental dataset). I do not know up to which level of
strain I can consider this curve as a linear elastic model to find E
(that can be used to calculate shear modulus).
I’ve seen in one book this can be
considered for e<3%. Unfortunately I could not remember which book
was that. Do you know a standard for this
assumption?
