Scarf angles, θ = 45°, 60° and 75° are employed. The bond thickness, t between dissimilar metals is controlled to be ranged between 0.1 mm to 1.2 mm. Finite element (FE) analysis is also executed to investigate the stress distributions in the scarf joints by ANSYS 11 code. From analytical solutions, stress singularity exists most pronouncedly at the steel/adhesive interface corner of joints having 45° to 75° scarf angle. This is not only in agreement with the FE analyses results but also confirmed by fracture surfaces observation wherein the fracture has always been initiated at this point. The strength of scarf joints increases as the bond thickness decreases. Interface corner toughness, Hc approach can be applied when predicting the failure stress of scarf joints. Besides, for scarf joints with an interfacial crack, the fracture toughness, Jc values are independent of bond thickness and less sensitive to adherends. Moreover, Jc increases as mode mixity increases. 2014-06-03T02:46:18Z 2014-06-03T02:46:18Z 2011-01 Article Key Engineering Materials, vol. 462-463, 2011, pages 768-773 1013-9826 http://www.scientific.net/KEM.462-463.768 http://dspace.unimap.edu.my:80/dspace/handle/123456789/35017 10.4028/www.scientific.net/KEM.462-463.768 en Trans Tech Publications
