SS04: Multiscale Modelling and Theory of Porous Media
Summary: The behaviour of micro-heterogeneous materials is mainly driven by the morphology of its microstructure and the interactions of the individual constituents. Due to limitations in computational power, it is nearly impossible to capture in computational simulations the discrete complex microstructures (such as porous microstructures) in all details. Thus, approaches like the mixture theory or the theory of porous media (TPM) are often used for an approximate description of complex porous micro structures. However, the main advantage of these effective macroscopic approaches is at the same time their main drawback, since only a little information about the microstructure is available on the macroscopic scale, e.g. volume fraction or permeability. It is the aim of this special session to bring together experts in nonlinear material modeling on several scales, in scale bridging as well as in the description of superposed continua in an averaged sense. This special session 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 of interest include (but are not limited to) multi-scale modeling, classical homogenization techniques and theoretical and numerical aspects for porous media models related to applications of various nature.
