Meeting 2020 TMS Annual Meeting & Exhibition
Symposium Fatigue in Materials: Fundamentals, Multiscale Characterizations and Computational Modeling
Sponsorship TMS Structural Materials Division

Scope This symposium features novel methods and new discoveries for understanding material fatigue and life prediction. It brings together scientists and engineers from all over the world to present their latest work on current issues in characterizing and simulating fatigue damage; identification of microstructural weak links; enhancement of fatigue strength and resistance; quantitative relationships among processing, microstructure, environment, and fatigue properties; and life prediction. This symposium provides a platform for fostering new ideas about fatigue at multiple scales and in multiple environments, numerically, theoretically, and experimentally. The symposium will be organized into six sessions:

• Data-Driven Investigations of Fatigue
• Multiscale Modeling Approaches to Improve Fatigue Predictions
• Microstructure-based Fatigue Studies on Additive-Manufactured Materials (Jointly organized with AM Fatigue & Fracture symposium)
• Fatigue Characterization Using Advanced Experimental Methods in 2D and 3D
• Multi-mechanical Interactions during Extreme Environment Fatigue Loading
• Crack Initiation Mechanisms and Short-Crack Growth Behavior

The proposed six sessions will be carried out over three full days, with morning and afternoon sessions each day. Throughout the six sessions, there will be an estimated 50 oral presentations, with 2-4 of those being keynote presentations. Additionally, a poster session will be held to supplement the oral presentations and to encourage student involvement. Students may submit an abstract for a poster presentation, an oral presentation, or both. Prizes for best posters will be awarded. A possible edited volume of extended articles on select topics discussed in this symposium will be evaluated during the meeting.
