Low-density porous materials are useful as lightweight constructional material due to have properties of lightweight, heat insulating and energy-absorbing. The porous materials have complex inner structure in comparison with dense materials. Feature of porous materials is the transformation of inner structure which emerges as macroscopic deformation behavior. Furthermore, the plastic deformation of cellular structure is mesoscopically occurred under the critical stress of cellular crush. Then we observe and evaluate the deformation of the materials in elastic limit because it is important for the analysis of their deformation problems, and it is shown that the nonlinearities of deformation behaviors can be eliminated by adopting the appropriate condition of experiment indicated in this paper.
