AbstractObservations are reported on the stress-strain behavior at - 9.5 + or - 0.5 degrees C of four types of ice obtained from the St. Lawrence River. The ice was subject to nominal rates of strain covering the range 2.1 X 10(-5) min(-1) to 5. 8 X 10(-2) min(-1). A ductile-to-brittle transition was observed for strain rate of about 10(-2) min(-1). In the ductile range the four types had an upper yield stress that increased with strain rate according to a power law.
