“…In the year 2017, a few studies were found on the active repair of metallic structures. For instance, Abuzaid et al ,,, used PZT patches for the repair of the plate through an experimental, numerical, and analytical method since it can be developed for metallic and nonmetallic materials of repair. However, in the next level of study, it can be possible to consider tubes/pipes or other types of structures for active repair because this type of structural repair has been found in passive repair .…”

Piezoelectric material transducers can work as an actuator or sensor. Generally, the actuator will be used to repair the structure, and the sensor will be used to find the health condition. In the last two decades, piezoelectric actuators have shown the capacity to lower and control the shear stress concentration and joint edge peel in adhesively bonded joint systems. Hence, this paper aims at reviewing the application of piezoelectric actuators in damaged structures and adhesively bonded combined systems based on three different repair investigation methods: analytical, numerical, and experimental. Moreover, the study also explores the delamination control of composite material beams and some other studies using a piezoelectric actuator. The specific aim of this work is to determine scientific challenges and future opportunities for considering piezoelectric materials in damaged structure investigations for novice researchers.

“…The influence of different hole patterns and crack locations, obtained as a result of the experiment under cyclic loading, was presented from the experimental samples modeled by the finite element method in ABAQUS. Abuzaid et al [27] studied the concentration and distribution of stresses in notched areas in piezoelectric actuators for an aluminum plate with opposite semicircular notches using the finite element method for external static loading.…”

Mathematical models of planar physically nonlinear inhomogeneous plates with rectangular cuts are constructed based on the three-dimensional (3D) theory of elasticity, the Mises plasticity criterion, and Birger’s method of variable parameters. The theory is developed for arbitrary deformation diagrams, boundary conditions, transverse loads, and material inhomogeneities. Additionally, inhomogeneities in the form of holes of any size and shape are considered. The finite element method is employed to solve the problem, and the convergence of this method is examined. Finally, based on numerical experiments, the influence of various inhomogeneities in the plates on their stress–strain states under the action of static mechanical loads is presented and discussed. Results show that these imbalances existing with the plate’s structure lead to increased plastic deformation.

This paper proposes a dynamic numerical model for the bonded-type ultrasonic motor considering the load transfer in the adhesive interlayer between the piezoceramics and the host structure. The finite element method and an extended shear-lag theory are used to derive the dynamic equation. The effectiveness of this model is validated by comparing the dynamic response of the stator in frequency and time domains between simulation and experimental results, with a maximum relative error of less than 4%. The dynamic load transfer in the adhesive interlayer is analyzed when the stator is excited electrically, and the results show that the interfacial load transfer is concentrated near the bonding edges. The effects of partially bonded piezoceramics on the dynamic characteristics of the motor are investigated, where two partially bonded conditions including edge and inner debonded cases are considered. The results indicate that both the inner and edge debonded conditions could reduce the vibration amplitude of the stator and then reduce the output performance of the motor.
