Detailed Description

CompositeElasticityTensor provides a simple RankFourTensor type MaterialProperty that can be used as an Elasticity tensor in a mechanics simulation.

This tensor is computes as a weighted sum of base elasticity tensors where each weight can be a scalar material property that may depend on simulation variables. The generic logic that computes a weighted sum of tensors is located in the templated base class CompositeTensorBase.
