Bruno Berthel is an alumni of École normale superieure de Cachan and holds a PhD in Mechanics from the University of Montpellier-II. He is Associate Professor at École Centrale de Lyon since 2008. He teaches Materials Science and especially durability-related issues. He carries out his research within the Tribology and System Dynamics Laboratory (LTDS) in the field of experimental and numerical study of crack nucleation and propagation under multiaxial fatigue loading with stress gradient (fretting and fretting fatigue application). He works particularly on the application of full field measurement techniques during mechanical tests (thermography and digital image correlation).
