Detailed Description

Base class for elastic isotropic materials with elastic modulus E and Poisson ratio v.

ElasticIsotropicMaterial is an abstract class. It provides the interface to which all elastic isotropic material implementations must conform. It also serves as a prototype for all elastic isotropic material implementations, as described by the Prototype pattern in {Design Patterns} by Gamma et al. (see https://en.wikipedia.org/wiki/Design_Patterns).
