Further to systematic experiments on the flexural strength of laboratory-grown, fresh water ice loaded cyclically, this paper describes results from new experiments of the same kind on lake ice harvested in Svalbard. The experiments were conducted at −12 °C, 0.1 Hz frequency and outer-fiber stress in the range from ~ 0.1 to ~ 0.7 MPa. The results suggest that the flexural strength increases linearly with stress amplitude, similar to the behavior of laboratory-grown ice.

湖冰的循环强化

在对实验室培养的循环加载淡水冰的抗弯强度进行系统实验的基础上，本文描述了在斯瓦尔巴群岛收获的湖冰上进行的同类新实验的结果。实验在 -12 °C、0.1 Hz 频率和约 0.1 至约 0.7 MPa 范围内的外纤维应力下进行。结果表明，抗弯强度随应力幅值线性增加，类似于实验室生长的冰的行为。
