Abstract:
Tests have been performed to compare the double- and single-shear
strengths of joints in DTD 546b light alloy sheets using Avdel
blind rivets. The tests were an extension of work done on solid rivets,
and followed conventional procedures.
The double-shear proof and ultimate strengths were found to
be appreciably better than the single-shear strengths over a useful
range of sheet thickness/rivet diameter ratio.
The effect of manufacturing tolerance was examined and
found to be important, though adherence to the rivet manufacturer’s
recommended procedures ensures good strength.
The above conclusions lead to a consideration of the
physical behaviour of the joints which is seen to differ in three
ranges of thickness/diameter ratio.
