Tensile test


The rivet joints supported 59 kN, the figure 1 show this. The struture stayed out of the range acceptable, 30- 40 kN. The team presumptions some reasons for this:
1)Was realized just one traction test
2) the specimens presented porosity in your structure. The rivet this problem did not occur.
3) The alumiun utized to do the rivets was cast many times , increasing your resistence
The figura 2 showed the comparation of cross section of the rivet and the specimens, showed the porosity.
The vídeo showed the traction test.
