Through analysis of the manufacturing process of the ring metal-net rubber and on the basis of the ring nesting model

in combination with nonlinear theory of dry friction and small curving beam model

the nonlinear constitutive relation of metal-net rubber was constructed

several metal-net rubber components of different relative density were taken on the compression experiment

and the experimental data were used to determine the coefficients on constitutive relation equation and compared with the experimental results. The results show that the model of the stiffness from nonlinear constitutive relation can correctly describe the nonlinear mechanical properties of metal-net rubber

and the theoretic calculations are consistent with the experimental data. The model can reflect the influences of the relative density

mesh size

mesh width and other such parameters

providing a theoretical basis for better design and application of metal-net rubber.
