Isotropic tangent modulus

Hi,
I have in my model material nonlinearity and contact nonlinearity, because I connect 3-4 components together. Thus I have to specify the plasticity under solid mechanics - Linear Elastic Material. If I do this, I need more material properties, as for example the isotropic tangent modulus.
What is this isotropic tangent modulus and how do I determine it? What impact this module has on the model?
Many Thanks.

Yasemin-
Tangent modulus is the slope of the stress strain curve after the yield strength has been exceeded. As this value is lowered to zero you approach a "perfectly plastic" material. Isotropic means there is no directional dependence on the property.
