@article { , title = {Acoustic emission method to study fracture (Mode-I, II) and residual strength characteristics in composite-to-metal and metal-to-metal adhesively bonded joints.}, abstract = {Failure behaviour of two types of adhesively bonded joints (composite-to-metal, metal-to-metal) has been studied under failure modes (Mode I: double cantilever beam (DCB) and Mode II: three-point end notch flexures (3-ENF)) using acoustic emission (AE) technique. The bonded specimens were prepared using two types of adhesive bond materials with three variations of adhesive bond quality. The effect of the presence of interfacial defects along the interface on the residual strength of the joint has also been studied. It was possible using the maximum AE amplitude method to select the AE events of mechanical significance. However, it proved difficult to propose a definitive AE trait for the mechanical phenomena occurring within specific AE event signals, for all adhesive types, bond qualities, and substrate configurations; therefore, all specimen combinations. There was a notable shift in spectral energy proportion as the AE source of mechanical significance varied along the specimen length for specimen combinations. However, it was difficult to confirm this distinctive trait for all specimen combinations due to difficulty in confirming the location and exact mechanical source. The proposed measurement technique can be useful to assess the overall structural health of a bonded system and may allow identification of defects.}, doi = {10.1080/00218464.2017.1278696}, eissn = {1545-5823}, issn = {0021-8464}, issue = {5}, journal = {Journal of adhesion}, note = {COMPLETED -- Still Latest Articles 26/1/2018, 21/12/2017, 7/12/2017, 22/9/2017, 21/8/2017, 24/7/2017, 26/6/2017, 23/5/2017, 25/4/2017, 24/3/2017, 21/2/2017, 26/1/2017 LM -- Info from contact 16/1/2017 LM ADDITIONAL INFORMATION: Faisal, Nadimul Haque -- Panel B}, pages = {347-386}, publicationstatus = {Published}, publisher = {Taylor and Francis}, url = {http://hdl.handle.net/10059/2103}, volume = {94}, keyword = {Adhesive materials, Destructive testing, Fracture mechanics, Failure modes, Interfacial fracture, Acoustic emission, Residual strength}, year = {2018}, author = {Droubi, Mohamad Ghazi and Stuart, Alan and Mowat, John and Noble, Craig and Prathuru, Anil Kumar and Faisal, Nadimul Haque} }
