Journal Title: Հայաստանի գիտությունների ազգային ակադեմիայի տեղեկագիր․ Մեխանիկա - Year 2013, Vol 66, Issue 3
Abstract
In the article the controlling of displacement of one-dimensional wave according to a depth in the piezoelectric medium of 6mm class is considered. Solutions of wave equation and characteristic equation of piezoelectric medium are presented in the form of Dalamber solution. Аfter satisfying boundary, initial and final conditions, the controlling action is determining.
