在这篇文章中，研究了一种新的设计策略，以提高双壳船舶的耐撞性，其中包括使用颗粒材料。在数值模拟中，采用离散单元法和有限元法耦合的框架研究了颗粒材料在单轴压缩过程中的承载能力。此外，还研究了颗粒的杨氏模量对载荷可转移性的影响。（©2016 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim）
In this contribution, a novel design strategy is investigated for improving the crashworthiness of double‐hull vessels, which involves usage of granular materials. For numerical simulation, a framework based on coupling of the Discrete Element and the Finite Element Method is used to study load bearing capacity of granular materials during uniaxial compression. In addition, the effect of Young's modulus of particles is also investigated with respect to the load transferability. (© 2016 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
