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.

由于材料的机械疲劳而导致的关键部件失效可能导致重大的材料和/或人员损失（例如：SW 1380-2018航班；植入物失效）。基础知识的不足阻碍了机械部件在重复载荷下的准确使用寿命预测。拟议中的加拿大研究主席专门旨在理解和量化目前缺失的疲劳特性，表面完整性和服务环境之间的关系，以及开发先进的测试和检查方法，以生成理论和数值建模所需的可靠数据。预计将应用于运输（飞机和桥梁）、生物医学（植入物）和能源生产（水电基础设施）。
