| Abstract: | The response of structure to shortduration impact is studied experimentally by employing explosively induced stress pulses in long aluminum bars containing central circular holes. The amplitude of the strain is measured in all cases. The effect of the direction of loading on the existing strain is also studied.It is concluded that the addition of more holes will decrease the dynamic stress concentration, especially if the direction of loading is from the smaller to the larger diameter holes. |
