The simulation of damage induced by a blast on a reinforced concrete wall is reported in this figure. The top of the figure shows the geometry of the wall as well as the position of the charge. The bottom of the figures reports the damage evolution at three time instants during the simulation. At the beginning the wall shows a failure that resembles the effect of a concentrate load with several radial cracks emanating for the center of the wall. Later damage concentrates at the bottom (where the wall is clamped) and the final failure mode is characterized by the complete shearing of the wall base.

Science is an essentially anarchic enterprise: theoretical anarchism is more humanitarian and more likely to encourage progress than its law-and-order alternatives — Paul K. Feyerabend.
Physics is like sex: sure, it may give some practical results, but that's not why we do it — Richard P. Feynman.
