✦ Synopsis

Stress pulse propagation in a semi-infinite viscoelastic solid of the Maxwell type is analyzed. The results show that a square stress pulse loaded at the surface develops into two wave fronts. The first wave front propagates with the dilatational wave velocity, while the propagation velocity of the second wave front depends on the relaxation time and Poisson's ratio. When the relaxation time decreases, the relative amplitude of the first wave front decreases. The first wave front disappears when the relaxation time is zero, and the second wave front propagates with the pressure wave velocity. When the relaxation time approaches infinity, only the first wave front exists, its shape approaching that of an elastic solid.
