| Abstract: | Experiments on rock dynamic properties relevant to impacting and blasting are oftenmade with a horizontal-impacting device, which can change loading stress waveforms and itsamplitudes. A computerized system of data sampling and processing used in the device is pre-sented in this paper, and some problems on this system are discussed. Finally, stress pulserecords and corresponding dynamic stress-strain-strain rate curves obtained using the systemfrom test with a granite rock have been presented. |
