Abstract: Open-cell foams are mainly used in the field of sound isolation and vibration absorption and as stuffing materials. Therefore, the theoretical study on their mechanical behavior, the relation between the mechanical properties and the density as well as the complicated microstructure is very important. In this paper, a brief review on mechanical models of open-cell foams is given. The emphasis is placed on the tetrakaidecahedron model and the random model which can reflect the characteristics of the actual cell structure. At the same time, the studies in this area in our country are specially covered and some future investigating trends are presented.

Key words: open-cell foam, mechanical properties, mechanical model
