Many researchers and engineers view mechanical fatigue of metals as a stagnated field, evidenced by the lack of substantially novel design approaches against fatigue in recent decades. However, our current capability to investigate, probe, and model the multiscale mechanisms of fatigue damaging processes may turn out to be pivotal for next-generation paradigms for the assessment of fatigue.
The use of 3D printed metal structures is taking a very fast ramp-up in industry. General Electric has demonstrated the possibility of printing titanium fuel injectors for their LEAP engine, EADS has printed a nacelle hinge bracket for the Airbus A320, Boeing is printing plastic inlet ducts for high-altitude aircrafts, hip implants and other prosthetics are exploiting the design freedom of additive manufacturing (AM),...
Sheet metal forming operations consist of simple bending, to stretching to deep drawing of complex parts. The mechanical properties of the sheet material greatly influence its formability, which is a measure of the amount of deformation the material can withstand prior to fracture. This blog post covers important definitions determining sheet metal characteristics, the test methods, and the equipment used to quantify them.
Experimental and Numerical Study on Fretting Fatigue Behaviour of Additively Manufactured Metal Parts
Some metals, particularly annealed low-carbon steel, or mild steel, show a discontinuity when transitioning from elastic to plastic deformation that produces the yield point phenomenon in the stress strain curve.

The Department of Engineering Science at Oxford University has recently obtained an iCASE studentship funded by EPSRC and Rolls-Royce plc to perform research into the mechanical behaviour of metals at high temperatures and high strain rates. The studentship provides full funding (fees and stipend) at the home / EU level for 3.5 years.
Virtual Fields Method for the dynamic behaviour
characterisation of metallic materials under purely inertial loads
Ecole Polytechnique and McGill are seeking two PhD candidates for a large project aiming at understanding the effects of shot peening on the fatigue lives of aerospace components. The project involves 8 PhD students that will be working in close collaboration. The project is co-funded by the Canadian goverment and 5 leading aerospace companies located in Montréal. Some projects involve internships at these companies.
We are seeking two students for the following projects:
