Transducers consisting of a strain gage or accelerometer and piezo-electric sensor are popular instruments used to evaluate dynamic response. Although the observation of transmitted strain by means of the strain gage method assures accuracy, it is not convenient to estimate the dynamic response of materials having a large cross-sectional area. On the other hand, there is little restriction in measuring of dynamic response using an accelerometer since it is small and light. It is easy to fabricate the transducer by applying a piezo-electric sensor. However, except for the strain gage method, the technological issues as to whether these are consistent or accurate for the measurements of dynamic response, particularly the impact load, have not been apparent. In this paper, we distinguish the technological issues which may arise in using such dynamic response transducers for measuring the impact load caused by the collision of two round bars or a sphere and flat plate.
