ALJOIN Figure 18 Results of the simulation of tearing tests of bolted joints – deformed structure
Figure 19: Tearing tests of bolted joints - comparison of measured and computed load
versus displacement curves
Bolted tubes subjected to axial impact
The work performed consisted mainly in:
• Selection of standard aluminium extrusions to be provided by ALCAN for the
preparation of the samples;
• Definition of small-scale sample geometry to obtain tubular bolted structures for
dynamic impact testing (see Figure 20);
• Design of the experiments: a fractional-factorial design of experiments using
orthogonal arrays was selected. The factors comprise: the material and temper
condition (AA 6005-T6 and 6008-T6), the number of bolts, and the impact
velocity
• Numerical analysis of the configurations selected.
