Modeling of deformation‐induced phase transformation during very high cycle fatigue (VHCF) using the boundary element method

PAMM, 2014
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.

Failure analysis of a woven composite under tension–compression very high cycle fatigue (VHCF)

Engineering Failure Analysis
In 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 ...

Investigation of the Fatigue Behavior of Austenitic Stainless Steels and Their Welds for Reactor Internals Under Combined Low Cycle (LCF), High Cycle (HCF) and Very High Cycle (VHCF) Operational Loading Conditions

Volume 6B: Materials and Fabrication, 2018
The fatigue assessment of safety relevant components is of importance for ageing management with regard to safety and reliability of nuclear power plants. Reactor internals are subjected to thermo-mechanical fatigue induced by operational temperature transients and to flow induced vibrations.
