This project is part of a larger project aiming at developing efficient laser cleaning processes for bridges. This project will take place at the University of Sydney and at ANSTO where the student will be conducting X-ray diffraction and neutron diffraction experiments to measure residual stresses at different depth on laser ablated steels. The student will need to establish a protocol to have repeatability and reliability of their measurements. The other part of their work will consist in performing finite element analysis to predict residual surface stresses from different laser settings and to predict the effect of sample preparation methods on the relaxation of residual stresses. The predictions will allow validation of samples that will be used to determine the mechanical properties of the laser ablated steels (especially in term of fatigue life) that will be conducted in another part of this larger project. To be able to work at ANSTO, the applicant will need to be willing to be subjected to a clearance check.
We are looking for applicants with background in materials science/engineering, mechanical engineering or structural engineering. Applicants with a physics background are also welcome.
