A comparison of open cell and closed cell properties for low-density materials

Richard M. Christensen

Vol. 2 (2007), No. 7, 1299–1307
Abstract

The stiffness and strength properties for open cell and closed cell low-density materials are collected and compared. These are the theoretical predictions for the Kelvin cell type and the oct-tet cell type of open cell forms and of the closed cell form from the generalized self-consistent method. The strength properties considered are those for plastic collapse and elastic instability, under both uniaxial stress and dilatational stress conditions.
