How to Deal with Very High Cycle Fatigue (VHCF) Effects in Practical Applications?*
Materials Testing, 2012Abstract Fatigue designing of high-stressed engine components is a key factor for reliable power train systems in automotive industry. In this context load assumptions are very important since this is attended with a pre-designing of important machine elements.

Abstract In the present investigation high-frequency fatigue tests on welded specimens with trimmed surfaces were carried out by means of an ultrasonic fatigue testing system (UFTS). The wave-like distribution of the load amplitude along the longitudinal axis of the UFTS specimens with a maximum in the minimum cross-section (at about the half length)

Failure analysis of a woven composite under tension–compression very high cycle fatigue (VHCF)
Engineering Failure AnalysisIn this work, the tension–compression response of a carbon fiber woven composite is investigated in the Very High Cycle Fatigue (VHCF) regime through axial ultrasonic testing. To enhance the stress-to-displacement ratio with respect to standard straight bars, hourglass-shaped specimen was proposed in a previous work, with, however, the failure ...

Abstract Many components have to withstand a very high number of loading cycles due to high frequency or long product life. In this regime, the period of fatigue crack initiation and thus the localization of plastic deformation play an important role.

AbstractA microstructural simulation model is proposed which accounts for damage accumulation in shear bands and deformation‐induced martensite formation in a metastable austenitic stainless steel (AISI304). The model is numerically solved using the two‐dimensional (2‐D) boundary element method.
