Abstract


As result of this study, the maximum stress of the studied electrical wire made of copper is significantly higher than that of the wire made of aluminum, it is also noticed that copper wire have a plastic behavior which undergoes mechanical deformations unlike the fragile behavior of aluminum wire. However, we have concluded that the critical life fraction of aluminum wire is higher than that of copper wire.
