Wave Propagation in Rock Under Blast Loads

Application ID: 12811

Transient analysis of the wave propagation in rock mass caused by a short duration load on the surface. Such loads are typical during tunnel constructions and other excavations using blasting.

The model shows the use of the Low-reflecting boundary conditions to truncate the computational domain to a reasonable size. The results are in very good agreement with those presented in the following reference:
