Abstract

The classical continuum model does not describe the mechanical behaviour of cellular materials. To model the size-dependent mechanical properties of these materials, the extended continuum models such as the micropolar approach can be used. The reference data is extracted from the virtual experiments performed on an artificial open-cell foam specimens. With the proper set of the Cosserat parameters the detailed microstructural model can be described on the macroscopic level using the extended continuum approach. The parameter identification task is defined as a minimisation task, which is solved using the evolutionary computational framework.
