Compressive mechanical behavior of multiple wire metal rubber

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.
