✦ Synopsis

The fictitious absorption method [1] is developed to solve convolution-type integral equations, specified in a system of sections and generated by dynamic problems of the excitation of a piezoelectric crystal by a system of strip electrodes. Compared with other approaches this method enables solutions to be constructed with high accuracy simultaneously in all the regions in which the integral equations are specified, including the boundary, and can be used at any frequencies.

## Abstract This paper addresses the development of the DXDR method by introducing a modified fictitious time (MFT) increment. The MFT is determined by minimizing the residual force after each iteration. The rank of the convergence rate shows the advantage of the new method. The results obtained fr
