Abstract EN
The behavior of a fine-grained piezoelectric coating/substrate with multiple Griffith interface cracks under electromechanical loads is investigated.
In this work, double coupled singular integral equations are proposed to solve the fracture problems.
Both the singular integral equation and single-valued conditions are simplified into an algebraic equation and solved by numerical calculation.
Thereby, the intensity factors of electric displacement and stress obtained are used to obtain the expression of the energy release rate.
Furthermore, numerical results of the energy release rate with material parameters are demonstrated.
Based on the obtained results, it could be concluded that the energy release rate is closely related to the size of the interface cracks and the mechanical-electrical loading.
For a bimaterial structure, the fine-grained piezoelectric structure exhibited better material performance compared to the large one.
