Summary: The behavior of porous materials is mainly driven by the underlying microstructure. Due to limitations in computational power, it is nearly impossible to capture the discrete porous micro structure in computational simulations. Thus, homogenization approaches (like the mixture theory, the theory of porous media (TPM) or the Biot theory) are used to describe the complex and strongly coupled material behavior. However, the main advantage of these homogenization approaches on the one hand is also their main drawback on the other hand, since only limited information about the microstructure is available on the macroscopic scale, e.g. volume fraction or permeability.

This special session will aim at bringing together experts in nonlinear material modeling on several scales, and colleagues dealing with homogenization approaches for porous media. It will provide a forum for researchers to develop and exchange fruitful ideas and to enhance knowledge on the modeling and computational aspects of the subject. Topics will include (but will not be limited to) multi-scale modeling in the FE approach, combined with classical homogenization techniques and algorithms, and solutions for multi-scale porous media models related to applications of various nature.
