About this Symposium

Topics of interest include (but are not limited to):
1. Microstructure-based Fatigue Studies on Additive-Manufactured Materials (JOINT SESSION with Fatigue in Materials Symposium)
2. Fatigue Modeling and Prediction
3. Data Science Techniques for Fatigue and Fracture
4. Novel Fatigue and Fracture Test Techniques (e.g. High-Throughput)
5. Critical Flaw Size Investigations
6. Effects of Surface Roughness, Residual Stress, and Environment on Fatigue and Fracture
7. Qualification and Certification for Fatigue and Fracture Applications
8. Processing and Structure Effects on Macroscale Fatigue and Fracture Properties and Performance (see details below)

Processing-structure-property-performance relationships pertinent to this symposium must focus on fatigue and fracture and can include the following. Processing includes machine settings (e.g. layer thickness), melt parameters (e.g. energy density, scan strategy), post-processing (e.g. heat treatment, surface treatment), and feedstock variables (e.g. flowability, spreadability, particle size distribution) that can directly impact fatigue and fracture performance of parts. Structure includes crystallographic microstructure (e.g. texture, phase content, grain size/morphology), internal defects (e.g. pores, inclusions), external defects (e.g. surface roughness), residual stress, and chemistry. Properties include all macroscopic fatigue and fracture properties (e.g. high-cycle fatigue, low-cycle fatigue, linear elastic fracture toughness (KIc), elastic-plastic fracture toughness (J-int), fatigue crack growth rate, and impact toughness (Charpy)), but do NOT include small-scale mechanical property assessment. Performance includes any end-product testing.
