Method and device for dynamic modelling of rubbery materials applied to human soft tissues. Part I: determination of mechanical characteristics and dynamic model proposal

Abstract

The paper aims to study the dynamic behaviour human soft tissues, based on the similarity noticed between the tensile stress-strain curves, for soft biological tissues and rubbery materials. Elastic materials, like rubber and steel, were tested for different types of loadings. In order to establish a dynamical model, the force-elongation dependency of the rubber wire is required. A rubber wire was loaded axially by increasing loads and the deformations up to more than 100% strains were registered. The experimental points from force-displacement plot were interpolated and the function proposed was chosen.
