Abstract

This paper deals with a realistic stranded cable model which takes into account not only the helicoidal construction of the cable but also the actual tangential compliance of the interwire contact patches, assuming an elastic material behaviour. Jn accordance with the theory of contact mechanics, it is shown that this involves shearing, micro-slipping and ultimately full slipping of the mating contact patches as bending increases and this translates into a decreasing cable flexural rigidity. On account of these phenomena, it is concluded that actual cable flexural rigidity is significantly lower than the maximum, rigid, single body value, however small is the bending. Finally, it is shown that the predicted flexural rigidity for vibrating cables agrees reasonably well with experimental results reported in the literature.
