Abstract：By simplifying the microstructure, knitteddapped metal rubber material was equivalent to a composite system assembled by loops in seriesparallel form. According to the characteristics of the stiffnessdeformation curve, the compression deformation process was divided into three phases including linear phase, nonlinear phase, and highorder nonlinear phase. Constitutive models were established and mathematical expressions for stiffness and compressive load were deduced. The models containing the basic technics parameters, such as metal wire diameter, elastic modulus, wire density could explain the physical nature of mechanical characteristics of knitteddapped metal rubber. The models were validated by the comparison of experimental data and calculated results. The result showed that the models were valuable for the analysis of the mechanical behaviors of knitted dapped metal rubber. It provides theoretical support for further studying mechanical characteristics and guiding design of the material.
