Loading and fracture response of CFRP-to-steel adhesively bonded joints with thick adherents – Part I: Experiments

Loading and fracture response of CFRP-to-steel adhesively bonded joints with thick adherents – Part II: Numerical simulation

“…Damage mechanics permit the simulation of step-by-step damage and fracture at a pre-defined crack path or arbitrarily within a finite region up to the complete structural failure, with the use of cohesive or interface elements. The available techniques for damage modeling can be separated into local or continuum approaches [14] (see Fig. 1).…”

“…The present work is the second part of a paper series, that is focused on the investigation and study of the loading and fracture response of CFRP-to-steel adhesively bonded joints. The seven SLJ cases whose fabrication and testing is presented in the first part [26] have been considered herein for numerical simulation. The main objective of this study is to provide justifications of the experimentally measured response, by examining the developed stresses and their variation through the loading history.…”

Effect of jig constraint state during welding process on fatigue properties of Al/CFRP dissimilar welds and fatigue life evaluation based on singular stress

“…Recently, primarily in consideration of environmental issues, transportation equipment designers and manufacturers have been promoting multimaterial designs into which lightweight metals and resin materials have been incorporated, and dissimilar material welding methods are now being developed to produce such multimaterial structures 1,2 . Currently, joining widely dissimilar materials is most commonly accomplished via adhesive bonding, 3,4 mechanical fastening 5,6 and combinations of both joining technologies. Developments are also being sought for ways to improve the resulting joint strength 7 …”

Feasibility of mechanical clinching for joining aluminum AA6082-T6 and Carbon Fiber Reinforced Polymer sheets

“…Nevertheless, adhesive bonding comes with a series of drawbacks, including the non-uniform distribution of stress and strain along the bonding length [30], and the debonding generally initiating at or near one of the bond terminations [31]. The shear strength of adhesive bonds increases with the square of the bonding length [32].…”
