Abstract

Abstract Due to complex mesoscopic and the distinct macroscopic evolution characteristics of ice, especially for its brittle-to-ductile transition in dynamic response, it is still a challenging task to build an accurate ice constitutive model to predict ice loads during ship-ice collision. To address this, we incorporate the conventional multi-yield-surface plasticity model with the state-based peridynamics to simulate the stress and crack formation of ice under impact. Additionally, we take into account of the effects of inhomogeneous temperature distribution, strain rate, and pressure sensitivity. By doing so, we can successfully predict material failure of isotropic freshwater ice,iceberg ice, and columnar saline ice. Particularly, the proposed ice constitutive model is validated through several benchmark tests, and proved its applicability to model ice fragmentation under impacts, including drop tower tests and ballistic problems. Our results show that the proposed approach provides good computational performance to simulate ship-ice collision.

基于多屈服面塑性状态的周动力模型及其在冰-结构相互作用模拟中的应用

由于冰的细观结构复杂，宏观演化特征明显，特别是冰在动力响应中的脆性向延性转变，建立准确的冰本构模型来预测船冰碰撞过程中的冰载荷仍然是一项具有挑战性的任务。为了解决这一问题，我们将传统的多屈服面塑性模型与基于状态的周动力学相结合，模拟了冰在冲击下的应力和裂缝形成。此外，我们考虑了非均匀温度分布、应变速率和压力敏感性的影响。通过这样做，我们可以成功地预测各向同性淡水冰、冰山冰和柱状盐水冰的物质破坏。特别地，提出的冰本构模型通过多个基准试验进行了验证，并证明了其适用于模拟冲击下的冰破碎，包括落塔试验和弹道问题。实验结果表明，该方法对模拟船冰碰撞具有良好的计算性能。
