Analysis of Electro-Thermal Characteristics of a Conductive Layer with Cracks and Holes
Electro-thermal characteristics of conductive layer with edge crack and internal hole subjected to steady current has been studied numerically. In this paper, an attempt has been made to determine the effects of presence of edge cracks or internal hole in conductive layers with different parameters by finite element method using COMSOL Multiphysics Simulation. The characteristics are evaluated in terms of electrical and mechanical parameters that can be expressed in terms of electric potential and temperature at different locations of the layer. The result shows that the generated temperature profiles are affected by edge crack or internal hole in a conductive layer. The effects of practical issues are also being analyzed which include variable crosssection, various materials, variable material properties, electrical and thermal insulation etc.
