Abstract

Abstract: This work presents the experimental characterization of multiple wire metal rubber material (MW-MR). MW-MR is a novel damping solid made of two kinds of coil entangled wires using a modified manufacturing process. Three batches of MW-MRs with different weight percentage ratios have been fabricated and tested under cyclic quasi-static loading and different maximum strains. Tangent modulus and loss factor are tested. The experimental results show that the weight percentage ratio can significantly affect the global mechanical compression properties. A microelement model of MW-MR was proposed for the first time, this model was based on the manufacturing process and then simplified by introducing the "equivalent factor" λ, a qualitative analysis based on the microelement model of MW-MR about the test results was made. The conclusions derived from the tests provide a new way for designers to adjust the mechanical properties of metal rubber. Graphical abstract: Image 1 Highlights: The quasi-static test results show that the tangent modulus and loss factor of multiple wire metal rubber samples change as the weight percentage ratio varies. The theoretical microelement model proposed in this paper points out that the equivalent factor and microelement quantity are key factors of the multiple wire metal rubber which is first proposed in this paper.
