Pressure Evolution

In the present paper an algorithm for frictional contact between two elastic bodies is presented. The algorithm is applied to the calculation of the evolution of contact pressure between two elastic bodies when material is being removed by fretting. To this end Archard’s law of wear is implemented into the algorithm. It is noticed that the calculated pressures after a period of fretting differ considerably from the initial Hertz type pressures. Further, it is noted that numerical instabilities can occur in explicit type wear calculations, and a stability criterion is suggested.

Induced Structure

In this research, the features of electro-induced periodical structures in the volume of LiTaO3 thin plate were theoretically and experimentally investigated. For the theoretical and experimental investigations, the calculations based on the finite element method and measuring of the surface acoustic wave (SAW) interaction were implemented simultaneously. The observed difference of the electro-induced structures provides a new opportunity to control of the acoustic wave propagation in a ferroelectric substrate. The volume-existed periodical structures were induced as different electric potentials were applied to the surface arranged electrodes. The features of the induced structure were theoretically investigated based on a developed theoretical unit cell model for different induced structure configurations. The properties of the acoustic wave interaction with the periodical structure were studied on the basis of a theoretical full 3D model of an SAW device. A novel controllable SAW device was fabricated and studied experimentally. The experimental results show significant differences in magnitude and phase of both reflected and transmitted signals depending on the induced structure configuration.
