Averaged strain energy density estimated rapidly from the nodal stresses by FEM for cracks under mixed mode loadings including the T-stress contribution
Meneghetti, Giovanni; Campagnolo, Alberto; Berto, Filippo (Journal article; Peer reviewed, 2019)The present contribution reviews a recently proposed method to rapidly estimate the averaged SED at the tip of short as well as long cracks under in-plane I+II and long cracks under out-of-plane I+III mixed mode loadings. ... -
Calibration of the potential drop method by means of electric FE analyses and experimental validation for a range of crack shapes
Campagnolo, Alberto; Meneghetti, Giovanni; Berto, Filippo; Tanaka, Keisuke Ke (Journal article, 2018)In experimental fatigue tests, it may be necessary to identify the onset of crack initiation, which is often defined at a given (short) crack length. Different experimental techniques are available to estimate the initiated ... -
Crack initiation life in notched Ti-6Al-4V titanium bars under uniaxial and multiaxial fatigue: Synthesis based on the averaged strain energy density approach
Meneghetti, Giovanni; Campagnolo, Alberto; Berto, Filippo; Tanaka, Keisuke (Journal article; Peer reviewed, 2017)The fatigue behaviour of circumferentially notched specimens made of titanium alloy, Ti-6Al-4V, has been analysed. To investigate the notch effect on the fatigue strength, pure bending, pure torsion and multiaxial ... -
Local strain energy density to assess the multiaxial fatigue strength of titanium alloys
Berto, Filippo; Campagnolo, Alberto; Welo, Torgeir (Peer reviewed; Journal article, 2016)The present paper investigates the multiaxial fatigue strength of sharp V-notched components made of titanium grade 5 alloy (Ti-6Al-4V). Axisymmetric notched specimens have been tested under combined tension and torsion ... -
Multiaxial fatigue strength of titanium alloys
Berto, Filippo; Campagnolo, Alberto; Welo, Torgeir; Vantadori, Sabrina; Carpinteri, Andrea (Journal article; Peer reviewed, 2017)The present paper investigates the multiaxial fatigue strength of sharp V-notched components made of titanium grade 5 alloy (Ti-6Al-4V). Axisymmetric notched specimens have been tested under combined tension and torsion ... -
Notched Ti-6Al-4V titanium bars under multiaxial fatigue: Synthesis of crack initiation life based on the averaged strain energy density
Meneghetti, Giovanni; Campagnolo, Alberto; Berto, Filippo; Tanaka, Keisuke (Journal article; Peer reviewed, 2018)The fatigue life of notched components subjected to multiaxial loading conditions may be influenced by extrinsic mechanisms operating during crack propagation phase, such as sliding contact, friction and meshing between ...
