The report considers the behaviour of glued sheets under alternating stress and gives the results of fatigue tests carried out on Redux glued joints having an overlap of 22 mm. The test pieces, which included untreated and aged joints, were subjected to alternating and intermittent stress in a range of cycles from 0.25 static strength to a million. The values obtained during these tests are compared with those of other authors. The occurrence of fatigue rupture in metal-metal glued joints is then discussed, as well as the effect on fatigue strength of the various ageing treatments used for some of the test-pieces. In conclusion, the fatigue strength values for glued joints are compared with those for riveted joints. Author
