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.

由于材料机械疲劳引起的关键组件故障可能会导致重大材料和/或人类损失（例​​如：FLGHT SW 1380-2018；植入物故障）。不足的基本知识阻止了重复载荷下机械组件的准确服务寿命预测。拟议的加拿大研究主席专门旨在理解和量化疲劳性能，当前缺失的表面完整性和服务环境之间的关系，以及开发为生成可靠数据的高级测试和检查方法，以进行理论和数值建模。预计将在运输（飞机和桥梁），生物医学（植入物）和能源生产（水力发电基础设施）中应用。
