    Nyckelord :FEM; SPR; self-piercing rivets; self piercing rivets; LS-dyna; Explicit FEM; lap-shear; cross-tension; KS2; r-adaptivity; 2D axisymmetric; axisymmetric;

    Sammanfattning : The automotive industry is currently trying to replace the conventional steels to lightweight materials such as aluminum or carbon fiber to meet all stricter emission targets. When using such materials, traditional joining methods, such as spot welds, could be difficult to use. Therefore, more focus has been put on self-piercing rivets (SPR). LÄS MER

    Sammanfattning : In the automobile industry, there is a big push for the automotive car manufacturers to base engineering decisions on the results of Computer Aided Engineering (CAE) solutions, and to transform the prototyping and testing, from a costly iterative process to a final verification and validation step. The variability in components material properties and environmental conditions together with the lack of knowledge about the underlying physics of complex systems often make it impractical to make reliable predictions based on only deterministic CAE models.
