Dynamic Crushing of Cellular Solids: Deformation Modes and Energy Absorption

结构和材料的能量吸收行为对于减少意外碰撞造成的损害和死亡至关重要。细胞固体在这方面非常出色。该项目旨在系统地研究蜂窝和金属泡沫这两种材料的动态破碎。将开发适用于这些材料的实验技术，并进行全面试验。研究了它们的动态变形模式和相关的能量吸收行为。这些发现将扩展我们对一类类似问题的概念理解，并将有助于设计具有细胞固体的结构，以大大提高耐撞性能。

Energy absorption behaviour of structures and materials is essential in minimising damage and fatalities caused by accidental collisions. Cellular solids are excellent in this respect. This project aims to systematically investigate the dynamic crushing of two such materials: honeycombs and metal foams. Experimental techniques applicable to these materials will be developed and comprehensive tests will be conducted. Studies will be made into their dynamic deformation modes and the associated energy absorption behaviour. The findings will extend our conceptual understanding of a class of similar problems and will help to design structures with cellular solids for much improved crashworthiness performance.
