Modified pendulum hammer in impact tests of adhesive, riveted and hybrid lap joints
A Komorek, J Godzimirski - International Journal of Adhesion and …, 2021 - Elsevier
This paper presents a modified pendulum hammer adapted to test the impact strength of lap
joints. The impact tests of lap specimens exhibited greater repeatability in terms of the
results, compared with the tests of block specimens (specimens used in Block Shear Test
(ISO 9653)). The modified testing device also allowed for testing of rivet and hybrid rivet–
adhesive joints. The comparative tests showed that the impact strength of the hybrid
connections was greater than the sum of the impact strengths of the adhesive and rivet …
