The report is concerned with a Voigt material, which corresponds to a model having a spring and dashpot in parallel. The problem of longitudinal wave propagation in a semi-infinite rod which is initially unstrained and at rest and whose end is given an impulsive velocity, which is then maintained, is considered. Formulae for the stress and velocity distributions in the rod are obtained and their values are plotted against time for different positions in the rod and against position in the rod for different times, dimensionless coordinates being used.
