This article is aimed at comparing two models based on the same assumptions to analyze the failure of adhesively bonded joints. These models combine the use of two criteria: a stress criterion for the initiation of micro-cracks and an energy criterion for the propagation of these micro-cracks to create a macro-crack. The first model only requires elastic calculations but the second is a continuum damage model. It is shown that the comparison of the two models against experimental results permits to describe in a correct manner the effect of geometrical parameters on the strength of a bonded joint.Read less <
