“…A two-level thermodynamic based micromechanics theory for domain switching in 1e3 piezocomposites is proposed to predict the orientation dependency of the electromechanical coupling behavior of the composite system [20,21]. The electromechanical load transfer in 1e3 piezocomposites with an imperfect interface has been studied and a theoretical model has been developed using Displacement Discontinuity Method (DDM) to evaluate multiple interface cracks in 1e3 composites [22,23]. The behavior of 1e3 piezocomposites under pure electrical loading condition at room temperature has been studied and it shows the dependency of fiber volume fraction when subjected to these loading conditions [24].…”

“…Experimental studies are effective in verifying theoretical results. The effective properties of piezoelectric composites on the interface material are reported by using theoretical and numerical methods in [24,25]. Andrianov et al [26] focus on the evaluation of the homogeneous properties of the active layers in both 31 and 33 MFCs.…”

This work presents the nonlinear dynamical analysis of a multilayer d31 piezoelectric macrofiber composite (MFC) laminated shell. The effects of transverse excitations and piezoelectric properties on the dynamic stability of the structure are studied. Firstly, the nonlinear dynamic models of the MFC laminated shell are established. Based on known selected geometrical and material properties of its constituents, the electric field of MFC is presented. The vibration mode-shape functions are obtained according to the boundary conditions, and then the Galerkin method is employed to transform partial differential equations into two nonlinear ordinary differential equations. Next, the effects of the transverse excitations on the nonlinear vibration of MFC laminated shells are analyzed in numerical simulation and moderating effects of piezoelectric coefficients on the stability of the system are also presented here. Bifurcation diagram, two-dimensional and three-dimensional phase portraits, waveforms phases, and Poincare diagrams are shown to find different kinds of periodic and chaotic motions of MFC shells. The results indicate that piezoelectric parameters have strong effects on the vibration control of the MFC laminated shell.

“…Material models for active composite systems which sustain local damage are found in the literature but they are scarce and those found focus on specific mechanisms. Martinez and Artemev [28] performed finite element analysis of a piezoelectric monolayer with broken fibre, while Sapsathiarn et al [29] modelled piezoelectric composites with imperfect fibre interface using an analytical method which utilizes Fourier integral transforms. A porous matrix on the other hand was considered by Della and Shu [30] to predict the overall effective properties of piezoelectric composites with the Mori-Tanaka model.…”

Electroelastic woven composites are modelled with a transformation field analysis to determine the overall mechanical and electrical responses taking into consideration the progression of internal damage. The solution is found for a representative volume element of the composite material in terms of constant stress concentration factors, which quantify the local stresses caused by overall mechanical loads, and constant influence functions, which quantify the effect of local stress transformations such as those caused by electric fields. The effect of damage in limiting or eliminating local stresses is determined in terms of auxiliary transformation stresses. An example for a three-dimensional woven composite with piezoelectric filaments in the warp fibre direction shows that the computed electric displacement deviates from linearity with applied load at the onset of local damage. The indication of damage through electric displacement is more detectable when loading and electric measurement directions are not aligned. Local damage mechanisms show different effects on the magnitude of electric displacement. Damage within fibre bundles in the warp, weft, and z directions by sliding or splitting has the most significant effect on the electric displacement.
