AsymptoticExpansionHomogenizationElasticConstants

Postprocessor for asymptotic expansion homogenization for elasticity

Description

This PostProcessor computes where is the homogenized elasticity tensor. It is used in conjunction with the Stress Divergence Kernel and the Asymptotic Expansion Homogenization Elastic Constants Kernel to compute homogenized elasticity tensor values according to where is the elasticity tensor. See Hales et al. (2015).
