Project: The role of defects on the dynamic fragmentation behaviour of additively manufactured materials
Supervisors: Prof Daniel Eakins
Additive manufacturing (AM) technology presents an extraordinary opportunity for materials in extreme dynamic environments. As AM moves from a novel manufacturing technique into the mainstream, the importance of understanding the physical/mechanical properties of this new class of AM materials, and their corresponding behaviour under impact is increasing.
This project will investigate the dynamic failure response of additively manufactured metals and alloys, with a view to understanding how specific defect types typical of the selective-laser-melting (SLM) process affect the development and character of damage under high-rate loading. A combination of detailed pre- and post-test characterisation, coupled with state-of-the-art high-speed visible and synchrotron X-ray imaging will be used to develop an overall picture of damage evolution in SLM materials, which in turn will help underpin new models for damage and failure. This project is also being conducted in collaboration with Sandia National Laboratories, with opportunities to perform hypervelocity impact experiments at their unique STAR facility.
This project offers the opportunity to undertake ground-breaking research in the field of impact engineering, involving materials science, mechanics, and ultrafast diagnostics.
Prospective candidates will be judged according to how well they meet the following criteria:
• A first class honours degree in Engineering, Physics or Materials Science
• Excellent English written and spoken communication skills
The following skills are also highly desirable:
• Ability to program in Matlab or similar
• Strong laboratory-based skills
Informal enquiries are encouraged and should be addressed to Prof Daniel Eakins ([email protected]
Candidates must submit a graduate application form and are expected to meet the graduate admissions criteria. Details are available on the course page of the University website.
