Submodeling of a stacked sheet metal assembly

Sheet metal stampings stacked and fitted on top of each other and secured together via mechanical fasteners such as bolts or rivets are commonly used in the automotive industry. Examples include seat belt anchors and seating track assemblies. The submodeling capability in ABAQUS facilitates economical, yet detailed, prediction of the ultimate strength and integrity of such jointed assemblies. A global model analysis of an assembly is first performed to capture the overall deformation of the system. Subsequently, the displacement results of this global analysis are used to drive the boundaries of a submodeled region of critical concern. The submodeling methodology provides accurate modeling that is more economical than using a globally refined mesh in a single analysis.

dude refine the mesh, its a simplistic model, crank it up. You will bet better results that way
