Experimental study of the effect of dynamic loading on rectangular armed panels made of self-compacting composite fiber and lattice sheets

The nature of dynamic loading is different due to the high force in a few milliseconds with static loading. The amount of energy absorption and energy loss in composite materials is a suitable measurement to evaluate the performance against impact loads. On the other hand, the use of self-compacting...
