Effective elasticity tensors and distance in the 21D space
We elaborated the concept of effective elasticity tensors based on the distance in the 21D space of these tensors.
Our formulation is based on norms in that space, which allow us to quantify the concept of proximity between the measurements and models.
This concept diminishes restrictions of the Hookean idealization and extends its applicability to seismic data contaminated by experimental errors.
