A novel experimental approach for the assessment of size effect in VHCF
, 2016 The continuous increment of the required design lifetime for many machinery components and the experimental evidence that materials could fail at stress amplitudes below the conventional fatigue limit have led to a growing interest in the study of the Very-High-Cycle Fatigue (VHCF) behavior of materials.

Microstructure-sensitive HCF and VHCF simulations
International Journal of Fatigue, 2013Abstract This paper provides some background and historical review of how microstructure-sensitive finite element simulations can play a role in understanding the effects of stress amplitude, R -ratio, and microstructure on fatigue crack formation and early growth at notches, including pores and non-metallic inclusions for Ti alloys and Ni-base ...

Challenges für the experimental investigation of VHCF of polymer composites
, 2011 Testing in the Very High Cycle Fatigue (VHCF) regime for polymer composites faces new challenges. Though composites are sometimes compared to metals they are totally differ-ent with respect to microstructure and fatigue behaviour.

Fatigue and Fracture Behavior of MMC in the HCF- and VHCF-Regime
Materials Science Forum, 2014Aluminum matrix composites (AMCs) are characterized by improved mechanical properties in comparison to their unreinforced matrix alloys. But the knowledge about the fatigue behavior of AMCs in the HCF-and in the VHCF-regime is limited until now. Due to this AMC225xe and AMC xfine225 with an average SiC particle content of 25 vol.-% and particle sizes ...
