Detailed Description

CompositeEigenstrain provides a simple RankTwoTensor type MaterialProperty that can be used as an Eigenstrain tensor in a mechanics simulation.

This tensor is computes as a weighted sum of base Eigenstrain 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.
