Abstract
This article proposes a novel soft magnetic entangled metallic wire material(SM-EMWM) for the first time, and describes the manufacturing and quasi-static tests of its samples produced from soft magnetic metal wires. The mechanical properties of three batches of SM-EMWMs with different porosity have been investigated at different maximum strains in different external magnetic fields. The result shows that its properties (tangent modulus, loss factor) can be tunable in the magnetic field rapidly and reversibly. Compared with no magnetic field condition, the tangent modulus of SM-EMWM samples in a magnetic field of 500 mT can increase 2 ∼ 7 times on the average, while the loss factor averagely raises 10% ∼ 30%. The results show that the application of SM-EMWM, as a novel magneto-sensitive smart material, is feasible and applicable.
