...Takashi Nakamura; Gaoge Xue; Yuma Kon; Nao Fujimura; Takuya Yamazaki; Nobuyuki Tonozaki; Akihisa Takeuchi; Masayuki Uesugi; Kentaro Uesugi ABSTRACT The very high cycle fatigue (VHCF) phenomenon has been recognized and extensively studied in the past quarter century. One of the most peculiar...

... for lightweight structures because of their high strength-to-weight ratio. For a reliable design, the fatigue performance in the very high cycle fatigue (VHCF) regime must be understood. Therefore, this study deals with the influence of frequency on VHCF properties as well as fatigue damage evolution in AlSi7Mg...

... it is generally recognized that multiaxial stresses occur in many full-scale structures. Nowadays, the growing need for greater lifespans forced the study of material behavior under what is nowadays very high cycle fatigue (VHCF) regime, fatigue research beyond 10E07 up to 10E10 cycles. However, most classic...

...Meysam Haghshenas; Jutima Simsiriwong ABSTRACT Ultrasonic fatigue testing has been extensively employed to assess the mechanical behavior of most engineering materials in the very high cycle fatigue (VHCF) regime (i.e., the number of cycles to failure beyond 10 7 cycles). Additionally...

...Guocai Chai; Jens Bergström; Christer Burman ABSTRACT In the very high cycle fatigue regime, fatigue crack initiation in high-strength steels is usually correlated to a subsurface inclusion with a fine granular area (FGA). Localized stress–strain concentration at the subsurface inclusion...

...Danièle Wagner; Johann Petit Fatigue devices working at high frequency (20 kHz) allow now to explore the fatigue domain with a total number of cycles much higher than 10 7 cycles in reasonable times. In that case, lifetime belongs to the very high cycle fatigue (VHCF) domain. As for low and high...

...Bernd M. Schönbauer; Michael Fitzka; Matias Jaskari; Antti Järvenpää; Herwig Mayer ABSTRACT Fatigue testing at ultrasonic frequency is a powerful method for rapid generation of high and very high cycle fatigue data. High accuracy of cyclic loading is the basis for reproducible test results, which...

... in high cycle fatigue (HCF) and even very high cycle fatigue (VHCF) regimes. As a result, it is paramount to systematically investigate those components’ fatigue behavior under both HCF and VHCF conditions. However, HCF and VHCF performances of SLM-Ti-6Al-4V alloy are still not fully understood because...
