Research for Constitutive Relationships of Metallic Rubbers with Various Structural Parameters

Static experiments were made for hollow cylindrical metallic rubber. Through parameter identification and curve fitting, for the three conditions in which only densities are various, only shape factors are various, and densities and shape factors are both various, respectively, theoretical prediction equations of constitutive relationship of metallic rubber were obtained. The three theoretical prediction equations were compared with each other. It showed that theoretical prediction equations in the case of various densities and shape factors had universe applicability. Theoretical prediction equations for the two conditions in which only densities are various, and only shape factors are various are special cases of that for the condition of various densities and shape factors.
