| Popis: | Adhesively bonded composite (ABC) joints used in the composite structures are modeled using 1D and 2D elements to generate the finite-element mesh. The present modeling technique has captured the overall structural behavior of ABC joints precisely. The analytical study proposed a novel failure criterion of ABC joints after understanding the structural behavior of joints through the modeling approach. A failure criterion developed based on the principle of conservation of energy stored within the adhesive layer by virtue of its allowable strength properties and consumed by applying stress per a unit load. The ultimate failure load of joints of popular configurations is estimated based on the principle of conservation of energy. The 1D–2D finite-element modeling approach has revealed the presence of a new form of mechanical energy named as the Bond energy concealed within the adhesive layer. A new failure mechanism and their modes are explained through the novel failure criterion. The numerical valu... |
