abstract: Body couples between the layers of wire were introduced and taken to be proportional to the body force between the layers with a coefficient of friction as the constant of proportionality. These friction coefficients were taken to be free parameters a sequence of numerical experiments. The results were unconvincing and although they suggest that the changes were at least not in the wrong direction, they are not recommended as a solution to the problem. A more detailed investigation is warranted which carefully considers the number of contact points between the layers and direction in which the frictional forces act.
problem_statement: Multistrand cables are used for overhead electrical lines, ropes, and suspension cables. The maximum sustainable stress on such cables directly impacts, for example, how well electrical lines will perform during an ice storm. Good models have been developed in the case where there is no friction; the goal is to start work in the more realistic case of friction.
