| 摘 要： | 以多孔材料理论为基础,干摩擦非线性理论为依据,并结合小曲梁模型建立金属橡胶材料的非线性本构关系,对空心圆柱形金属橡胶材料的静态试验结果进行拟合,得到非线性本构关系模型中的各项系数与密度的变化关系式,从而实现对该材料在密度发生变化情况下的本构关系的预估。

| Abstract: | On the basis of theory of porous material and dry friction,and combining with the model of small curved beam,nonlinear constitutive relation of metal-rubber was constructed.Static compressive experiments were made for hollow cylinders of metal-rubber.Experimental data were sorted out for curve fitting,then relations between all the coefficients in constitutive relation and the density of the material were obtained.Eventually constitutive relation of the material was predicted successfully. |
