Abstract [en]

The ACM 2 spot weld model is the currently most widely used spot weld model in industry. It is designed to be tuned using parameters to represent the stiffness characteristics of a spot weld in a suitable way. The choice of these parameters is however often associated with uncertainties. Therefore, the set of parameters with best performance is determined by employing an updating algorithm. Further, the result is compared to a new category of models, the so called Spider models, which intend to overcome mesh dependence in the spot weld area by re-meshing the structures locally. The results are formulated as guidelines for the optimum implementation of these spot weld models for structural dynamics. The studies are performed using two cut-out parts from a Volvo FH truck cabin. In addition, a new analytical approach for updating material data of isotropic shell structures is derived and the equations are verified using the same test pieces.
