Abstract: Based on the Sherwood-Frost equation and characteristics of the material, the constituent parts and forms of the constitutive equation for the knitted-dapped metal rubber considering temperature effect are discussed. According to the quasi-static compression experimental data gained at different temperatures, the parameters for the constitutive equation are obtained by fitting. Considering the experimental data of different specimens with different densities at different temperatures, numerical simulations are conducted to validate the constitutive equation. The results show that the simulation results are in good agreement with the experimental results. The obtained constitutive equation can satisfy the requirements for estimation of the quasi-static compression constitutive relation of the knitted-dapped metal rubber at high temperature.
