Abstract
In this paper, the dynamic electromechanical response of a coated piezoelectric strip with a crack under an anti-plane mechanical and an in-plane electric impact loads is investigated. The crack is oriented normally to the interfaces. Based on the integral transform techniques, the present problem is reduced to the solutions of singular integral equations. Numerical calculations are carried out, and the main results presented are the variations of the dynamic stress and electric displacement intensity factors, the dynamic energy density factors versus time as functions of the geometric parameters and electromechanical loads.
