Abstract: Abstract The paper deals with new non-proportional biaxial experiments and corresponding numerical simulations to analyze the load-history dependence on damage and fracture behavior of ductile metals. The numerical simulations are based on a phenomenological, thermodynamically… read more here.

DOI: 10.1520/jte20170147
Abstract: In this article, it was shown that for high cycle multiaxial fatigue life prediction, models based only on material parameters in the form of fatigue limits of component loadings should not be used. This is… read more here.
