Advances in  Experimental Impact Mechanics

Metallic materials are ubiquitous and indispensable to daily life due to their excellent manufacturability as well as their relatively high strength and ductility. Some metallic materials also exhibit notable corrosion resistance, weldability, recyclability, and reusability, which renders them suitable for broad applications such as architecture, food, medical, civil, energy, automotive, aerospace, and defense industries.

 In such applications, components made of metallic materials may be subjected to abnormal or extreme mechanical environments ranging from low-speed drop to high-speed impact, crash, shock, or explosion.

Assessment of safety and reliability of components under such conditions becomes paramount, with the dynamic stress–strain response including failure and fracture being key parameters. The material response information can be used to develop strainrate-dependent material models to enable predictive simulations to evaluate the safety and reliability of a component under extreme conditions.
