Load passage for a rough contact on a granular mass and illustration of the maximum shear stress (obtained by finite element calculation) when the load is centred on the mass (CIFRE Safran Transmission Systems PhD by Guillaume Vouaillat).
Surface measured with roughness meter (Amplitude ~1 µm, surface size ~ 600 µm x 480 µm)
- Numerical simulation of lubricated contacts
- Efficient solid mechanics calculations (composite materials with strong anisotropy, rough surfaces and viscoelastic materials)
- Analysis of surface damage in elasto-hydrodynamic contacts (taking into account the heat within the contact and granular modelling of materials)
