Computer simulation for the constriction resistance depending on the form of conducting spots

Abstract

The constriction resistance of conducting spots in a contact surface is one of the most fundamental problems of conduction on a steady current field. Although equations for the constriction resistance of conducting spots with simple circle and square shapes were derived, these are no equations for the constriction resistance of conducting spots with irregular shapes. While constriction resistance depends on the form of conducting spots, the problem has not been addressed; moreover, it is very difficult to pursue effective study in this matter. Computer simulation is a very suitable method for the above problem. In this paper, computer simulations, based upon the boundary element and Monte Carlo methods are carried out, and the constriction resistance of conducting spots of regular and irregular forms are analyzed. As a result, the behavior of the constriction resistance is clarified. >
