Dynamic Crushing of Cellular Solids: Deformation Modes and Energy Absorption

结构和材料的能量吸收性能对于最大限度地减少意外碰撞造成的损坏和死亡至关重要。多孔固体在这方面是极好的。本计画旨在系统地研究蜂窝与泡沫金属两种材料的动态破碎特性。将开发适用于这些材料的实验技术，并进行全面测试。将对其动态变形模式和相关的能量吸收行为进行研究。研究结果将扩展我们对一类类似问题的概念性理解，并将有助于设计具有蜂窝固体的结构，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.
