VHCF8 – 8th International Conference on Very High Cycle Fatigue

Aim & scope

After the 1980s epoch-making findings of internal fatigue fractures of high strength steel under numerous loading cycles, the very high cycle fatigue (VHCF) has been recognized as an emerging and unprecedented issue in the fields for material strength. These days, requirements for mechanical components and structures have been getting more demanding as represented by automobile engines, marine engines, turbine structures, high speed railway components, etc., and the reliability against the cyclic loading over 107 or even longer is regarded as one of the most important issue for strength design. Thus, improved understandings of the VHCF behaviors not only for metallic materials, but also for polymers and composites are essential to develop reliable fatigue life prediction methods. The Eighth International Conference on Very High Cycle Fatigue will focus on this topic.
