In this section, the dynamic propagation behavior of a penny-shaped interface crack in piezoelectric bimaterials is analyzed. The objective of this paper is to use the boundary conditions of the penny-shaped interface crack to study the dynamic propagation of the crack under the action of load, so as to provide some valuable implications for the fracture mechanics of the piezoelectric bimaterials and simulate the interface crack between piezoelectric bimaterials, it is necessary to establish a suitable model and give appropriate boundary conditions according to the actual situation. The elastic displacement and potential equations are constructed according to the structural characteristics of the circular crack. In the case of a given displacement or stress, the Laplace transform and Hankel transform are used to simplify the problem into an integral equation with unknown functions. According to the boundary conditions, the corresponding unknowns are obtained, and the closed solution is derived. The results show that the fracture toughness of a penny-shaped interface crack in piezoelectric bimaterials is related to the thickness of the material, the impact time, the material characteristics, and the electric field. At the same time, it can be found that different materials have different roles in the crack propagation, so it is very important to study the crack opening displacement (COD) intensity factor of the crack for safety design.

Purpose This study presents the outcomes of a finite element analysis (FEA) of forced vibrations by a time-harmonic loading of a bi-layered piezoelectric plate with two-axially pre-stressed layers. Methods The investigation is conducted based on the following assumptions: (i) the resultant system is resting on a rigid foundation, (ii) each layer is poled along the direction perpendicular to the free surface, (iii) a complete contact state exists at the interface of the plane in the plate, and (iv) the initial stress state at the layers is modeled based on the three-dimensional linearized theory of elasticity for solids under initial stress (TLTESIS). First, we describe nonlinear governing equations of motion and boundary-contact conditions for the dynamical model of the current system and then apply a linearization and non-dimensionalization procedure to the problem under consideration. In terms of Hamilton principle, a finite element model (FEM) is developed based on the weak form. Results and Conclusions The proposed and validated FEM approach can help to address several issues in the piezoelectric structure of finite lengths, either pre-stressed or not. In particular, we present an investigation of the effects of changing problem factors on the dynamic behavior as well as the frequency response of the composite plate. The numerical results demonstrate that the stress transition across the interface of the layers plays a key role in the resonance mode of the system, in both a quantitative sense and a qualitative sense.
