REL's SURE-Pulse Software processes the informationrecorded with oscilloscope software used in Split Hopkinson Pressure Bar procedures. This software isdesigned to analyze oscilloscope waveforms to deter-mine high strain rate testing results; such as: Stress,Strain, and Strain Rate.

SURE-Pulse Software directly integrates strain resultsfrom high-speed cameras displaying them in graphs.Different sample geometries can also be accommodated.

The SURE-Pulse software helps verify the system’s accuracy by including checks in the system to insure itis well aligned and calibrated.
