N2 - Various models of foam deformation have been formulated during last decade, but most of the models make use of basic concepts of continuum mechanics in combination with finite element method with limited consideration of specific micro-mechanisms of foam deformation and fracture. Three types of deformation and fracture mechanisms of oriented foams were classified: 1) Large reversible deformation, 2) Large elasto-plastic deformation and 3) Brittle fracture of faces and/or edges of individual cells. In this paper, five polymeric materials which have completely different deformation behaviors are selected and their fracture behavior was observed by scanning electron microscope. Among them, three polymeric foams with distinctively different deformation and fracture mechanisms are selected based on the classification for detail analyses.
