It is known that residual stress in a structure effect on the fatigue life, especially tensile residual stress make the life shorter. Recently aluminum alloys widely used as structural parts of auto vehicles. In industry, it is very important to simulate the residual stress in the aluminum alloy part for the fatigue design. In this paper, numerical simulations for residual stresses in 6000 series aluminum alloy during press forming processes were achieved with a large scale parallel computing finite element method, ADVENTURECluster[○!R]. Residual stress is in press formed structures are depended on coefficient of friction between jigs and works.
