Introduction Metallic rubber is not only a porous material, but also a dry-friction damping material.
It is difficult predicting nonlinear constitutive relationship of the material and computing response of damping system made of the material, which is forward positional task to be solved in the field of vibration engineering.

Samples were prepared using solid state reaction technique, suitable oxides alternatives of Tl2O3, NiO, SrO, CaO, BaO and CuO with 99.99% purity as raw materials and then mixed.
Even within completely crystalline materials, the degree of structural perfection can vary from one material to another depending on the method of preparation and purity.
