Riassunto analitico
The aim of the present thesis is to define a finite element methodology, in terms of strength and fatigue performance, of the new joining technologies used in the current and future Maserati S.p.A. vehicles. The process has been carried out with a correlation activity between the CAE evaluations and the experimental data, provided by Maserati, of a hybrid joining composed by two plates of steel and aluminium alloy joined by a Flow Drilling Screw (FDS). The FEM methodology has been developed with the focus on improving the virtual simulation accuracy for both fatigue and structural applications. The latter case studies the assembly response combining the FDS with adhesive bonding.
In both cases, the virtual environment relies on Hypermesh for the pre-processing of the model, and it differentiates between Nastran and nCode for the fatigue analysis and Abaqus for the non-linear static analysis with adhesive bonding.
