A smart single-lap adhesive joint integrated with partially distributed piezoelectric patches

Abstract: The powerful electro-mechanical coupling attribute of piezoelectric materials enables these materials to act as effective actuators. Using this attribute, a smart single-lap adhesive joint was developed by anti-symmetrically surface bonding piezoelectric patches onto a typical single-lap joint. The forces and bending moments at the edges of the developed smart joint can be adaptively controlled by adjusting the applied electric field in the piezoelectric patches, thus reducing the stress concentration in the j… Show more

“…This effect dominantly determines the stress distribution in the adhesive layer as indicated in previous studies; Roberts (1989); Cheng et al (1991); Cheng and Taheri (2005); Cheng and Taheri (2006); Cheng et al (2006a) and Cheng et al (2006b). Considering the proposed smart single-strap joint subjected to an axial force, as shown in Fig.…”

“…In their proposal work, Cheng and Taheri [57,58] showed that the control over the stress concentration at the adhesive joints can be achieved through the use of the piezoelectric actuator and the induced surface moment. The electric field in the actuator is applied in order to maintain, or reach, a desired stress distribution within the adhesive layer.…”

“…By taking the advantage of shape memory alloy (SMA) and PZT, the concept of intelligent reinforced concrete structure was proposed [ 64 ], in which SMA cables close the crack in the structure and embedded PZT patches are used to detect the onset and severity of cracks. Smart patches based on carbon fiber reinforced polymers with embedded PZT patches were investigated with the aims towards providing permanent and integral monitoring of structural and functional integrity as well as implementing as a structural health monitoring system using electrical impedance spectroscopy [ 65 , 66 ].…”
