Abstract

This paper describes a model for numerical prediction of surface temperature rise due to friction and electrical Joule heating between rough surfaces by means of discrete and continuous convolution fast Fourier transform (DC-FFT and CC-FFT). The contact resistance in non-conformal rough surface contact is defined. Steady and unsteady state surface temperature rises due to an imperfect electrical contact (ImPEC) are analyzed. The surface temperature rise computed is verified with existing experimental ImPEC result. The computational prediction of steady and unsteady state temperature rises in rough surface contact companying electrical current is expected to facilitate the understanding of interfacing sliding ImPEC and surface melting initiation.
