Remarks

Defines the material properties for an isotropic material. Note that the shear modulus G is defined in terms of the elastic modulus E and the Poisson's ratio nu as:

$G= \frac{E}{2(1+\nu)}$

Specifying a value for all three properties E, G and nu therefore results in an overdetermined material definition and must be avoided.
