Mechanical behavior of strands in CIC conductor analyzed by Monte Carlo method

The computer simulation of mechanical behavior of strands in a cable-in-con duit (CIC) conductor analyzed by Monte Carlo method has been carried out fo r analyzing the stability of the CIC Conductor. In the CIC Conductor, the m echanical behavior of strands during energizing has not been evaluated suff iciently and hence the quantitative evaluation of the frictional heating, t he contact stress between strands and the coupling losses that determine th e stability of a CIC Conductor have not been clarified. A CIC Conductor wit h 38% of void fraction were constructed in a computer by compressing the ca ble. In the Monte Cal lo method, the position of strands which were divided into mesh mere changed to minimize the potential energy. It could simulate the strand motion induced by the Lorentz force and the change of the conta ct stress distribution between strands. The method developed in this work is also used to calculate the load-displa cement curve of the cables and the position of strands. By using the method , it would be possible to estimate the stability of a CIC Conductor.
