Development of a multiaxial fatigue damage parameter and life prediction methodology for non-proportional loading

Sandip Suman, Alan Kallmeyer, John Smith

Most of the prior studies on the prediction of fatigue lives have been limited to uniaxial loading cases, whereas real world loading scenarios are often multiaxial, and the prediction of fatigue life based upon uniaxial fatigue properties…

Probabilistic fatigue S-N curves derivation for notched components

P. Raposo, J.A.F.O. Correia, A.M.P. De Jesus, R.A.B. Calçada

Europe has a number of ancient riveted metallic bridges, constructed during the second half of the 19th century up to the middle of the 20th century, which are still in operation. In this paper, a unified approach is presented to generate…
