摘要
•Please find below the highlights of the manuscript “Flexible Riser Tensile Armour Stress Assessment in the Bend Stiffener Region”:•A nonlinear finite element model is developed to account for the effect of the bend stiffener on the flexible riser response.•It is particularly investigated the stresses in the tensile armour wires for extreme and fatigue load cases.•The results are compared with the ones obtained from numerical models assuming no bend stiffener interaction and constant curvature. Comparisons are also performed with analytical models.•It is shown that the contact pressure between the bend stiffener and riser affects the stresses in the tensile armour wires.
