本文报道了从圣劳伦斯河获得的四种冰在- 9.5±0.5°C时的应力-应变行为。冰的额定应变速率为2.1 × 10−5 min−1至5.8 × 10−2 min−1。当应变速率约为10−2 min−1时，观察到韧脆性转变。在延性范围内，四种类型的屈服应力均随应变速率呈幂律增加。
Observations are reported on the stress–strain behavior at −9.5 ± 0.5 °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 × 10−5 min−1 to 5.8 × 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.
