| Abstract Scope |
Many applications in the aerospace and automotive industry demand the use of lightweight materials such as magnesium alloys to reduce weight and increase fuel efficiency. Still, in some critical sections, the use of much stronger materials such as steel is inevitable. Due to the large difference in melting points of steel and magnesium alloy along with their immiscibility in the liquid state, makes it impossible to join them using traditional welding techniques. Friction stir welding shows promising results in joining these dissimilar metals. Being a new technique, the failure mechanism of the joint needs to be investigated. In this work, a joint between AZ31 and DP590 steel is modeled using phenomenological crystal plasticity formulation on mesoscale. The interface of the two materials is modeled using cohesive elements. A parametric study has been performed to understand the effect of grain size and interface strength on the mechanical performance of the joint. |
