S16: Residual Stress in Fatigue and Fracture

Description

The Symposium supports exchanges of active research and facilitates the development of industrial guidance within professional societies including ASTM, ASM, and SAE.

Symposium topics include work related to the effects of residual stress on fatigue and fracture phenomena as well as techniques for the engineering and assessment of fielded systems. Relevant presentations will address topics that include, but are not limited to:

  • Experimental characterization of related phenomena (e.g., residual stress fields, fatigue, corrosion, sub-critical crack growth, and fracture)
    • Modeling to correlate and forecast residual stress effects on material damage (e.g., fatigue crack nucleation, corrosion, creep, crack growth, delamination)
  • Verification and experimental validation of related models
    • Manufacturing processes that affect the bulk (e.g., additive manufacturing, welding, forging, quenching)
    • Localized processes that affect performance in strength, durability, or damage tolerance (e.g., peening, burnishing, rolling, hole expansion, interference fits, nitriding, tumbling)
  • Changes of residual stress fields over time or due to exposure (e.g., thermal)
  • Work at all scales, to include approaches typically found in Materials Science as well as application Engineering (e.g., Mechanical, Aerospace, Structural, Civil)
  • Engineering methods for sustainment of fielded assets (e.g., probabilistic assessments, non-destructive testing, process control)

A journal special issue is contemplated for selected papers.
