Abstract: The failure due to accidental drop of magnetic recording disks made of brittle or ductile materials is of great interest in the design of small form factor hard disk drives. In this study, ...

Abstract: An impedance-based structural health monitoring technique is presented. By analyzing the in-plane vibration of a thin lead–zirconate–titanate (PZT) patch, the electromechanical impedance of the PZT patch is predicted. The ...

Abstract: This paper describes a generic impedance-based model for predicting the electromechanical (EM) impedance of one-dimensional (1D) and two-dimensional (2D) structure-piezoceramic (PZT) interacting systems. The vibration of ...
