“…The cantilever beam-type PVEH has a simple structure, a wider range of applications, and relatively higher output power [33,34]. The cantilever beam-type PVEH usually has a layer of piezoelectric patch bonded to the surface of the PVEH, or both the top and bottom surfaces [35,36]. Although this type of structure has many advantages, there are also many unavoidable drawbacks.…”

In this article, the piezoelectric patches are embedded into three‐dimensional (3‐D) braided composite material (BCM), and a 3‐D embedded braided composite piezoelectric vibration energy harvester (BCPEH) is designed. The 3‐D embedded BCPEH can be applied in more complex working environments to protecting the piezoelectric patches, and has a longer lifespan. The material parameters of the 3‐D BCM are obtained by analyzing the representative volume units (RVU). Using Hamilton's variational principle, the vibration control equation, and the output voltage and power expression are derived. The influence of excitation frequency, load resistance, and external excitation on the output voltage and power are simulated under different braided angles and embedded depths.

Purpose The purpose of this paper is to provide a theoretical analysis of the fracture behavior of multiple axisymmetric interface cracks between a homogeneous isotropic layer and its functionally graded material (FGM) coating under torsional loading. Design/methodology/approach In this paper, the authors employ the distributed dislocation technique to the stress analysis, an FGM coating-substrate system under torsional loading with multiple axisymmetric cracks consist of annular and penny-shaped cracks. First, with the aid of the Hankel transform, the stress ﬁelds in the homogeneous layer and its FGM coating are obtained. The problem is then reduced to a set of singular integral equations with a Cauchy-type singularity. Unknown dislocation density is achieved by numerical solution of these integral equations which are employed to calculate the SIFs. Findings From the numerical results, the following key points were observed: first, for two types of the axisymmetric interface cracks, the SIFs decrease with growing in the values of the non-homogeneity. Second, the SIFs increase with increases in interface crack length. Third, the magnitude of the SIFs decreases with increases in the FGM coating thickness. Fourth, the interaction between cracks is an important factor affecting the SIFs of crack tips. Originality/value New analytical dislocation solution in an FGM coating-substrate system is developed.

The present article deals with the investigation of elasto-dynamic response of a finite crack under normal and shear impact loading situated at the interface of two semiinfinite orthotropic strips. Laplace and Fourier Integral transforms are employed to reduce the transient problem to the solution of a pair of dual integral equations in the Laplace transform plane which are solved using iterations in the low frequency domain. The analytical expressions of stress intensity factors of the crack at the interface problem are found. To determine time dependence of the parameters, these equations are inverted to yield the dynamic stress intensity factors for some fiber-reinforced orthotropic composite materials using Bellman method and the method given by H.Dubner and J. Abate. The results are depicted through graphs for different particular cases. K E Y W O R D Sinterfacial crack, normal and shear impact loadings, normalized stress intensity factor
