Abstract:

Conclusions from an experimental and theoretical research program is used with a intermediate layer and the thickness of the directly loaded outer slab is smaller than the critical thickness, then this slab fails in a critical way. This means that a concentrated loading is created by the stream of particles which are ejected through the hole punched in the directly loaded slab. This concentrated load has a high energy content and dominates the failure process in the other parts of the structure. 2 No geometrical damping occurs in the stream of particles. 3 When the concentrated loading is formed, this loading cannot be distributed economically by increasing the stiffness and strength of the second layer, and the lower slab fails as a result of shearing.
