Modeling of packaging behavior in closed-cell aluminum foam.

The aim of this paper is to present the available modeling strategy available for description of the packaging behavior, which often takes place in the foams. The packaging process is modeled by means of approaches, which are used in the phase transformation theory. The constitutive model is based on the double-well elastic potential, which is defined for small strains. Two principal approaches are used for the research: discrete method based on the Voronoi tessellation and phase-field method. Discrete modeling approach is required for the estimations of the critical stresses in foams, which leads to the initiation of the packaging process. The phase-field approach is the continual approach, which is required for description of the packaging propagation in the foam. (© 2014 Wiley-VCH Verlag GmbH & Co.
