Abstract:
Some unusual near surface effects due to air blasts on a solid half-space are studied by an analytic treatment of the stress field in an elastic half-space subjected to a two dimensional uniform pressure applied suddenly and permitted to expand with a linearly decreasing velocity from an initial supersonic velocity. A partial solution is obtained in closed form by asymptotic methods. The results indicate the presence of very large gradients of stress in the neighborhood of the surface of the half-space as the velocity of the surface pressure approaches and passes through the velocity of P-waves.
