Main project: Crack deviation in Al alloys by Friction stir processing
Funding: ERC
Supervisor(s): Aude Simar

Lv Zhao completed his Master and PhD degrees in Institut National des Sciences Appliquées de Lyon in 2013 and 2016. His PhD work addressed the fracture behavior of solar grade monocrystalline and multi-crystalline silicon wafers, in which a couple of innovative experimental techniques have been elaborated and new results highlighted. He is now working in the framework the ERC Starting Grant ALUFIX as post-doc fellow with Professor Aude Simar. The aim is to investigate the crack propagation in aluminum alloys in the presence of local residual stresses induced by shape memory alloy particles. His work encompasses an experimental part in which metal matrix composites (MMCs) are manufactured by friction stir processing, and a numerical part in which the cohesive zone method is applied to address the crack path within the MMCs in the framework of finite element modeling.
