Viscoelastic behavior of athletics track surfaces in relation to their force reduction

The present paper is aimed at clarifying the dependence of the force reduction ability of sport surfaces used in athletic tracks on the material's viscoelastic properties and on the geometry of the sample. The study is based on laboratory tests carried out with an “artificial athlete” apparatus...

Description
Summary:The present paper is aimed at clarifying the dependence of the force reduction ability of sport surfaces used in athletic tracks on the material's viscoelastic properties and on the geometry of the sample. The study is based on laboratory tests carried out with an “artificial athlete” apparatus and dynamic mechanical analysis. Seven different sport surfaces were tested; other polymeric materials were also examined in order to widen the property ranges covered. The results show a prominent effect of sample thickness on the measured value of force reduction; a method to relate it to the intrinsic properties of the material is proposed.
