“…In literature, few studies are presented with the aim to optimize the FML configuration for given performance. What characterizes all of them is that they relate to optimization for a single specific condition, like vibration and damping characteristics or impact resistance . None of these studies considers the combination of multiple constraints related to different properties.…”

To further optimize aeronautical structures, an increased level of material hybridization is required. Optimization efforts aim to identify optimal design solutions that satisfy prescribed requirements. However, this demands reversal of currently available knowledge on hybrid structural technologies, which are often formulated as theories predicting performance based on known load cases and selected material configurations. After briefly reviewing the available fundamental theories for strength, fatigue, and damage tolerance of hybrid structures, this paper discusses the challenges in reversing these theories. Solutions are proposed in which theories can be approximated to significantly reduce the computational time while maintaining the required level of accuracy.

“…[16] using finite element method based on a nonlinear model for displacement field in the viscoelastic core layer of the beam structure. Power consumption and vertical displacement optimization of composite plates subject to a step load were carried out by piezoelectric patches using the modified multi-objective Elitist-Artificial Bee Colony (E-ABC) algorithm by Ghashochi-Bargh and Homayoune Sadr [17]. Hwang and Steeves [18] optimized the hybrid cores to minimize unit cell density given compressive and shear strength constraints for a variety of unit cell configurations.…”

Optimization of embedded piezoelectric sandwich nanocomposite plates for dynamic buckling analysis is presented in this work based on Grey Wolf algorithm. The Grey Wolf algorithm mimics the leadership hierarchy and hunting mechanism of grey wolves in nature. In addition, the main steps of hunting, searching for prey, encircling prey, and attacking prey are employed. The structure is composed of a laminated functionally graded-carbon nanotubes reinforced layers as core integrated with sensor and actuator layers considering structural damping effects. Two-dimensional magnetic and 3D electric fields are applied to core and piezoelectric layers, respectively. Sinusoidal shear deformation theory is utilized for obtaining the motion equations and differential quadrature method is applied for solution. Also, a proportional–derivative controller is employed to control the dynamic behavior of the structure. Finally, the optimum designs for the structure are evaluated using proposed Grey Wolf algorithm based on the geometrical parameters of plate, applied voltage, controller parameters, volume fraction of carbon nanotubes, spring, and shear constants of foundation. Numerical results indicate that by applying the positive voltage and transverse magnetic field the optimum dimensionless frequency of the system decreases.

“…Static and dynamic responses of piezoelectric plates have been investigated extensively in the past years (Alibeigloo and Kani, 2010;Behjatet al, 2011;Rezaiee-Pajand and Sadeghi, 2013;Ghashochi-Bargh and Sadr, 2014;Rafiee et al, 2014;Padoina et al, 2015). Moon et al (2007) designed a linear magnetostrictive actuator using Terfenol-D to control structural vibration.…”

Free vibration of a magnetoelectroelastic rectangular plate is investigated based on the Reddy's third-order shear deformation theory. The plate rests on an elastic foundation and it is considered to have different boundary conditions. Gauss's laws for electrostatics and magnetostatics are used to model the electric and magnetic behavior. The partial differential equations of motion are reduced to a single partial differential equation and then by using the Galerkin method, the ordinary differential equation of motion as well as an analytical relation for the natural frequency of the plate is obtained. Some numerical examples are presented to validate the proposed model and to investigate the effects of several parameters on the vibration frequency of the considered smart plate.
