Fatigue damage of advanced metallic materials

点击翻译按钮获取中文摘要

Failures of critical components due to mechanical fatigue of material can cause significant material and/or human losses (ex: flght SW 1380-2018; implant failures). Insufficient fundamental knowledge prevents accurate service life prediction of mechanical components under repeated loads. The proposed Canada Research Chair specifically aims at understanding and quantifying the relationships between the fatigue properties, the surface integrity and service environment which is currently missing, as well as developing advanced testing and inspection methodologies required to generate reliable data for theoretical and numerical modeling. Applications in transportation (aircrafts and bridges), biomedical (implants) and energy production (hydroelectric infrastructures) are anticipated.
