Use of inhomogeneous finite elements for the prediction of stress in rope terminations

An inhomogeneous element method of solving the strain and stress distribution of a cone‐like synthetic rope termination, which is designed and manufactured to enhance the strength of end connection of the rope, is described. The 8‐node quadrilateral isoparametric axisymmetric element was used. Different material constants were specified at different Gauss sampling points, so as to simulate the non‐homogeneity of the termination. The results indicate that maximum axial stress value in strand is much larger than the element average stress value. This element proved to be useful in calculating stresses and strains in reinforcing fibre strand embedded in resin matrix. The results obtained give some insight into the non‐uniformity of the stress distribution and will be meaningful to the designer of the rope end termination.
