Shakedown solutions for pavements with materials following associated and non-associated plastic flow rules [PDF]
, 2016 Existing lower-bound shakedown solutions for pavement problems are generally obtained by assuming that materials obey an associated flow rule, whereas plasticity of real materials is more inclined to a non-associated flow. In this paper, a numerical step-

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 11, Page 4372-4389, November 2024.Abstract Parts manufactured by wire arc additive manufacturing (WAAM) are characterized by a peculiar surface morphology, namely, surface waviness, that negatively affects the fatigue performance. To exploit the full potential of WAAM and minimize the need for postproduction work, it is crucial to utilize the components in the as‐built state.
