Steel cords have been in use as an important and convenient machine element for load and power transmission. Although the steel cords have been used through the ages, the fatigue damage mechanism of cords under bending has not sufficiently been elucidated. Especially, the friction force between the wires is important for the bending stiffness and the fatigue failures. In this study, the effect of friction on the failure initiation site was discussed performing some experiments and FEM analysis under cord bending condition.
