To check the adaptability of the assumption that the slip is proportional to the shearing load of that rivet, complete load-deformation graphs were plotted. The law of proportionality practically holds up to about 1/3 of the ultimate strength. Sunk rivets are ellastically stronger than ordinary rivets, e ?? pecially for thinner plates. The values of k for steel plates with steel rivets are about 1/3 of those for duralumin and well coincide with the relation of their proper elastic constants of materials.<BR>Spot-welded joints were also tested both for duralumin and stainless steel; the comparison of k's relating to their welded areas shows that the rigidity is of the same order as that of rivetted joints. Further, tests were extended to the combinations steel plates with duralumin rivets and duralumin plates with steel rivets, and the results show that k depends considerably on the material of rivet itself.
