“…The stress generated by the piezoelectric patches on the host structure can help to mitigate the stress concentration due to the external load. Different methodologies used for the active stress control and repair via the piezoelectric actuator [5][6]. Reduction of the stress concentration near notches and holes using the piezoelectric actuators was investigated by Rogers [7].…”

Stress control of structures by means of active smart material has evolved in recent years. The structure's stress control can typically be considered as strengthening that effects the structure's load-carrying capability. The stress-concentration cause by holes and notches produces a large variation and significant increase in stress. The control of the stress concentration and its distributions in the notched area is valuable for many practical and design applications. This study investigates the impacts of the piezoelectric actuators on control of the stress concentration factor (SCF) for an aluminum plate with opposite semicircular notches. Finite-element method (FEM) is used to access the SCFs due to external static loading. The stress control efficiency is assessed by the SCFs as an effectiveness criterion. The results indicate that SCFs reduces linearly with active piezoelectric actuator.

“…Crack is repaired under tensile and compressive forces distributed on the upper and lower layers of the delaminated beam. A brief survey on active control and repair of the structural crack using piezoelectric patches is presented (Abuzaid et al, 2015). Slope continuity and facture parameters are evaluated to measure the efficacy of repair of a crack in poly methyl methacrylate (PMMA) plate in the passive and active modes under static loading conditions (Liu, 2008).…”

This article presents an experimental investigation of repair of a crack in a structure using piezoelectric material under thermo-mechanical loading environment. The cyclic mechanical load is applied on a plate with a straight and angular crack under uniform temperature environment. Two cases have been considered for the repair of crack under (a) mechanical loading and (b) thermo-mechanical loading environment. A piezoelectric sensor is utilized to measure voltage. The measured voltage is used to calculate the stress intensity factor in passive and active modes. The effect of a single and double piezoelectric patch in the repair of the plate is investigated. The double piezoelectric patch is found to be more effective as compared to single patch when placed symmetrically offset from the crack. An optimal value of voltage and phase difference is evaluated for most effective crack repair. Location of the piezoelectric patch is varied with respect to crack location, and best-suited position for effective crack repair is proposed. The viability of piezoelectric used for repair under thermo-mechanical loading is discussed. The active mode of repair by piezoelectric is found to be effective under thermo-mechanical loading environment.

“…However, most recently researchers are exploring active repair involving smart materials such as piezoelectric actuator. Study of repair and stress control of mechanical structures and their electromechanical response had attracted the attention of many researchers (Abuzaid et al, 2015c; Wang and Wu, 2012). The converse effect of the piezoelectric actuator had made it possible to induce control moments and forces on the host structure.…”

This article proposes an alternative model for active repair for an edge-cracked plate with adhesively bonded piezoelectric actuator. It computes the Mode-I stress intensity factor (SIF) produced by the piezoelectric actuators using appropriate derived geometrical weight functions. Furthermore, this article presents an experimental study to verify the proposed analytical model and the finite element analysis using ANSYS software. Therefore, the analytical, finite element and experimental results for Mode-I opening of the crack conditions are demonstrated. Parametric analysis to understand the influence and to study the efficiency of the piezoelectric actuator on mitigation of the Mode-I SIF was conducted. The obtained analytical solution is applicable in the calculation of Mode-I SIF with reasonable accuracy. The result indicated that the maximum reduction of SIF is achieved with the application of high external voltage and thin thickness actuator. The relative errors of the analytical model and the experimental results are less than 10% in all the cases studied in this article.
