Research into the behaviour of materials in extreme dynamic environments, such as an explosive blast, is of continuing interest and importance. This PhD opportunity will investigate the effect of two shock impacts on two industrially important lightweight materials; aluminium and titanium. The first impact will be tailored to induce voids within the material but not fracture it, the second will recompact those voids. Materials characterisation and mechanical tests will investigate the changes to the properties of the metals induced by the impacts.
Shock impact is an extreme loading event and hence material response is vastly different to conventional loading scenarios, but is relatively poorly understood. One result of a shock impact can be spalling; the detaching of a flake of material from the back face of the bulk.
This project will look to generate early stage spall, ie nucleate voids within intact materials, and then investigate the resultant effects on the mechanical and microstructural properties when the metal is subject to a second shock impact, re-compacting the void region. Careful control of the initial impactor conditions, utilising shock recovery techniques, will enable the control of, and study the effects of, the dispersal of the voids (width of spall plane) and the density of the voids. In addition, the different crystal structures of the aluminium and titanium are expected to respond to the shock loading and re-compaction very differently.
This project offers the opportunity for studying the material and mechanical behaviour of important industrial materials in extreme environments.
