✦ Synopsis

Numerical results were extracted from the theoretical solution of the title problem for the case of the standard linear solid. The numerical procedure was accomplished by solving a second kind Fredholm integral equation and then by inverting the Laplace transformed intensity function. The latter was obtained by using the Papoulis-Miller-Guy method. The variation of the dynamic viscoelastic stress intensity factor vs time was evaluated under various material and geometrical parameters.
