This work investigates the effect of artificial surface defects on the fatigue limit of a 7050 Aluminum alloy (AlZn6CuMgZr). A large fatigue testing campaign under fully reversed plane bending loading is undertaken on ... -

The chip formation mechanism of the Ti-6Al-4V remains a challenging problem in the machining process as well as its modeling and simulation. Starting from experimental observation on the titanium alloys Ti-6Al-4V machining ...

Communication avec acte;AYED, Yessine; MAREAU, Charles; GERMAIN, Guénaël (AIP Conference Proceedings, 2018)
For metallic materials, fabrication processes (e.g. machining and forging) may involve important strain rates and high temperatures. For such severe loading conditions, the development of damage is often associated with ...

The numerical modelling of the behaviour of materials at the microstructural scale has been greatly developed over the last two decades. Unfortunately, conventional resolution methods cannot simulate polycrystalline ...
