Abstract An electromagnetic stress-wave generator which was developed to study shock waves in snow and ice is described. This system works on the principle of generating large electrical currents to produce highly transient loads on the test specimen. In its present configuration, the generator can produce pressures ranging from a few kilopascals to as large as 10 4 kPa and load frequencies as, high as 150 kHz. The system has been found to have high repeatability and has good turn-round time.
