Abstract
Spot welding used in four wheeler fabrication and repair works. It is one of the essential area where the design plays a vital role in identifying the mechanical behavior of different structures which are joint together and to impose the static, fatigue and impact strength of this joints at computer aided engineering technique by identifying the works which are to be concentrated during fabrication. This work is about determining the fatigue life of spot welded joint which are introduced which some boundary condition which could be used in mechanical structural analysis using CAE. Here the life of nugget which is subjected to fatigue loading is determined. In order to carry out analysis of sheet thickness and spot diameter geometry is considered to be essential parameter for proceeding the above suggested research work. Here ANSYS workbench is used to solve the required problem by using finite element analysis technique. Static structural works space is used to carry out the basic structural analysis of the rigid member which is joint together. Workbench is considered to be a user friendly tool compared with that of ADPL. In order to determine the fatigue life of spot welded joints before undergoing fabrication works this kinds of studies are carried out over here. The results acquired can be plotted in stress strain graphs where the characteristic curve helps as in solving our engineering constrains. The modeling of the part work are carried out the CREO softwar
