摘要: 在海冰试验研究的基础上 建立了一个海冰的数学模型,根据此模型推导出海冰的本构关系,并通过试验验证了此本 构关系的正确性. 根据海冰的本构关系拟合出海冰的最大抗压强度和应变率的关系曲线并推 导出海冰最大抗压强度和应变率关系的公式,并用试验数据验证了此公式的正确性.

Abstract: A mathematical model based on the actual state of oceanic ice is established. According to this model, the constitutive relation is derived and compared with the experiment of uniaxial anti-pressure strength. The formule for the maximum anti-pressure strength is derived to describe the relations between compressive strength and strain rate of oceanic ice, and is verified by tests. This formula can be used for related structural analysis.

Key words: oceanic ice, mathematical model, constitute relation, compressive strength, strain rate
