“…So, many studies to grasp and describe the fracture behavior of piezoelectric materials under electro-mechanical loading have been done. In most studies, the research orientation carried in general is on the mode of cracking; mode I as in [19,21,38], mode II as in [12] (for a composite laminates material), mode III as in [3][4][5]17,30,36], mixed mode as in [29], or on the model; Griffith model as in [14,21,42], Dugdale-Barenblatt model as in [8,15], or in the position of the crack in the structure; infinite plane as in [19,25], semi-infinite plane as in [8] (for a non-piezoelectric material) or still on the composition of the structure; only one material as in [25], bi-material as in [22,39].…”

“…The dynamic behavior of a Griffith crack situated at the interface of two bonded dissimilar FGPM is displayed in [34]. Chen et al [3] studied the transient response of a semi-infinite mode III interfacial crack propagating between piezoelectric-piezomagnetic materials. Shin and Lee [33] analyzed the dynamic propagation of a crack in FGPM interface layer between two dissimilar piezoelectric layers under anti-plane shear.…”

The main objective of this work is the contribution to the study of the piezoelectric structures which contain preexisting defect (crack). For that, we consider a Griffith crack located at the interface of two piezoelectric materials in a semi-infinite plane structure. The structure is subjected to an anti-plane shearing combined with an in-plane electric displacement. Using integral Fourier transforms, the equations of piezoelectricity are converted analytically to a system of singular integral equations. The singular integral equations are further reduced to a system of algebraic equations and solved numerically by using Chebyshev polynomials. The stress intensity factor and the electric displacement intensity factor are calculated and used for the determination of the energy release rate which will be taken as fracture criterion. At the end, numerical results are presented for various parameters of the problem; they are also presented for an infinite plane structure.

“…Interfacial defects, typically interfacial cracks and interfacial rigid line (a mathematical model used in solid mechanics to describe narrow hard phase, which can be produced in the interface due to the chemical aliquation, aging and corrosion), are inevitable in manufacturing and using. A large number of researchers have focused on dislocation, cavity, crack and interfacial crack . The interaction of multiple defects has been further studied.…”

The interaction between generalized screw dislocation and two asymmetrical interfacial secondary cracks emanating from an elliptic blunt crack tip in magneto‐electro‐elastic solid is investigated. Utilizing the complex potential method, the closed‐form solutions for complex potentials and generalized stress fields are derived. In some limiting cases, the present solutions can reduce to the well‐known results. Moreover, many new solutions for special cases are discussed. The energy release rate at the right interfacial secondary crack tip and the image force acting on dislocation are also calculated. Numerical calculations are given for analyzing the effects of variable parameters, such as location of the dislocation, materials constants and geometrical parameters of interfacial secondary crack. The results show that the long left interfacial secondary crack or the blunt crack with the high passivation rate enhances the influence of the dislocation on the energy release rate at the right interfacial secondary crack tip. In addition, the energy release rate increases with the increment of elastic coefficient of the other half‐plane, but decreases with the increment of dielectric coefficient or magnetic permeability coefficient.

“…Among the pursued nanoscale fillers, carbon nanomaterials, one-dimensional (1D) carbon nanotubes (CNTs) and two dimensional (2D) graphene nanosheets (GNs) in particular, have received great attention coupled with extensive development effort due to their exclusive chemical structures and tunable electrical properties [6][7][8][9]. In the past decades, CNT-and GN-based nano-fillers with low percolation threshold and appropriated electrical loss have already demonstrated dramatically enhanced microwave absorption performance in the pursed composites [10][11][12][13][14].…”

Abstract. Absorbing materials are developed with the concept of "thin, light, wide and strong", and various methods and materials have been attempted to satisfy the demand. In this work, the in situ growth method were conducted to grow reduced graphene (RGO) into carbon fiber (CF) to prepare CF-RGO composites. Moreover, the phase, microstructure and electromagnetic performance of the flexibility and lightweight composites were characterized. Consequently, the XRD and SEM results indicate the RGO is well grown on the surface of CF. The microwave absorption performance of the as-prepared samples were calculated, and the results show that the effective absorption band of the composites move towards low frequency once the RGO were introduced into the CF.
