Tape winding angle influence on subsea cable sheathing fatigue performance
Viespoli, Luigi Mario; Panza, Luigi; Johanson, Audun; Alvaro, Antonio; Soma, Aurelio; Berto, Filippo (Peer reviewed; Journal article, 2020)A fundamental component of subsea power cables is the thin galvanized steel tape winded around the dielectric and sheathing layer in order to prevent permanent thermal cycling induced deformation. The pressure state induced ... -
Tensile and fatigue behavior of a Pb-Sn-Sb alloy investigated via small-scale in-situ mechanical testing in SEM
Wan, Di; Viespoli, Luigi Mario; Johanson, Audun; Hagen, Anette Brocks; Berto, Filippo; Alvaro, Antonio (Peer reviewed; Journal article, 2020)Pb-Sn-Sb alloys (E-alloy) are commonly used in subsea power cable sheathing. Due to the relatively low melting temperature, i.e. around 600 K, this type of alloy is prone to experience microstructural time-dependent evolution ... -
Tensile characterization of a lead alloy: creep induced strain rate sensitivity
Viespoli, Luigi Mario; Johanson, Audun; Alvaro, Antonio; Nyhus, Bård; sommacal, alberto; Berto, Filippo (Journal article; Peer reviewed, 2018)The aim of this work is to investigate and define the tensile properties of cable sheathing lead alloy. In particular its strain rate sensitivity due to the pronounced creep already present at room temperature, in relation ... -
Toward Risk-based Inspection of Hydrogen Technologies: a Methodology for the Calculation of the Damage Factor of Hydrogen Embrittlement
Campari, Alessandro; Alvaro, Antonio; Ustolin, Federico; Paltrinieri, Nicola (Peer reviewed; Journal article, 2023)Hydrogen is considered a promising energy carrier to achieve the ambitious target of a zero-emission society in the forthcoming years. Despite its environmental advantages, hydrogen-induced material damages represent a ... -
Viscous regularization for cohesive zone modelling under constant displacement: an application to hydrogen embrittlement simulation
Yu, Haiyang; Olsen, Jim Stian; Olden, Vigdis; Alvaro, Antonio; He, Jianying; Zhang, Zhiliang (Journal article; Peer reviewed, 2016)The convergence problem during the cohesive zone modelling of hydrogen embrittlement in constant displacement scenario is attributed to the numerical instability which is studied analytically in the present work. The ...
