The static constitutive model of fiber reinforced cellular materials

Fiber reinforced cellular materials (BFRCMs) are prepared with fiber content of 0.2% (in volume). The quasi-static compression experiments have been carried out, the stress-strain curves have been worked out and a new math model has been created to establish the static constitutive model of BFRCMs. The results indicate that, BFRCMs have the successively sized cellular structures and a wide plateau stage in the static stress-strain curve, and BFRCMs are ideal energy absorbing material; the static constitutive relation has good coherence with stress-strain curves; the static constitutive model of BFRCMs can be applied in practical projects and numerical simulation. Thus it can be seen, the new math model has broad application prospects in the static constitutive model of cellular materials.
