Two parametric parallel strand cables modelling of a socket-type termination for high tenacity

The present study concerns the shape optimization of a socket-type cable termination, in order to define the optimum geometry which leads into a linearly decreasing axial stress along the cable. The goal of this paper is to prove that it is possible to create a single material termination which obtains the aforementioned distribution of stresses due to its geometry and at the same time eliminates the stress concentration effect at the cable entry. The importance of the casing’s geometry and its impact on the distribution of the stresses is revealed in the analysis of casings different geometry. An axisymmetric model with two design parameters was developed and analyzed.
