Fig. 3. Snapshots of dynamic disturbances moving in rectangular reinforced concrete specimens with two EDI sources and (a) two (PRC-05/02) or (b) no (PRC-05/03) dummy holes, generated by the numerical simulations. No fracture criterion is incorporated, and contours of volumetric strain at time (top) 20, (middle) 60 and (bottom) 100  s after the simultaneous application of EDI are illustrated for the lower quarter part.
