摘要：
This paper deals with the mathematical description of metal matrix syntactic foams (MMSFs). MMSFs are advanced materials having promising application fields in aviation, transport and automotive industry, in civil engineering and in many other industrial fields. They are porous materials having low density and relatively high compression strength especial compared to 'conventional' metallic foams. The characterization of MMSFs is continuously developing but the mathematical description of the compressive stress-strain curves is still missing partially. However these formulas are needed to numerically model the non-linear response and energy absorption of the MMSFs in case of compressive loading. According to this the aim of this paper is to give a full, but relatively simple method to handle the compressive stress-strain curves. © Periodica Polytechnica 2011.
