Influence of density on the electrical behaviour of a steel metallic wool

The aim of this paper is to present the influence of density on the electrical behaviour of steel metallic wool. The electrical conductivity – density curves follow a power-law relationship. The exponent of the power-law is varying from 2.5 to 3.5 with the initial density. This evolution is correlated to the variation of the exponent of the power law describing the stress-density curves.
