Summary
In this paper we present an experimental technique and a numerical procedure to measure the short-time relaxation functions of nonlinear viscoelastic media. The experimental technique consists of a longitudinal stress wave propagated through a pretensioned bar, while the numerical procedure incorporates experimental data into the solution of aVolterra type integral equation.
