THE "NUTCRACKER" ICE STRENGTH TESTS--1969-70

Field tests using the nutcracker ice testers measured ice crushing strengths in the range 600 to 900 psi. Approximate deflections at failure (peak stress) were in the range 0.6 to 2.3 inches. The tests were conducted in Tuktoyaktuk Harbour where the ice was brackish with salinities up to about 3 grams/kg (i.e. parts per thousand). The results did not appear to be very sensitive to variations in loading rate in the range 200 to 1,500 psi/minute. Doubling the leg diameter did not significantly reduce the nominal ice failing stress. /Author/
