Numerical Distribution of Temperature as a Guide to Investigation of Melting Point Maximal Front Spatial Evolution During Resistance Spot Welding Using Boubaker Polynomials

Abstract

In this study, we are concerned with the temperature distribution inside the central nugget during a particular sequence of resistance spot welding (RSW). Numerical calculations are issued from an attempt to solve heat transfer equation inside the heated device. Boubaker polynomial expansion scheme has been applied to the main system solution expressed in cylindrical coordinates and which is solved using the Householder-QR/QL algorithm. The melting point maximal front spatial evolution has been monitored in order to make comparison with precedent results.
