Abstract: The structure of foam materials is analyzed. It is noted that foam materials under uniaxial tension and compression have different strain diagrams. A simplified physical model for a heteromodular foam material in the form of a steel ring is proposed. The model was tested on a Walter + Bai AG LFM-L-1 test machine. The deformation of the model was analyzed using the ANSYS Workbench software package taking into account the contact interaction between its elements. The calculation results were compared with experimental data.

Keywords: heteromodularity, experimental study, contact task, finite element method.
