The external nonstationary load acting on an electroelastic bimorph (metal-piezoceramics) beam with split conductive coatings is identified. Use is made of the Laplace transform. The original functions are recovered analytically. The unknown quantities are determined by solving a system of Volterra equations © 2011 Springer Science+Business Media, Inc. Source

A numerical-analytic method for the identification of the axisymmetric mechanical shock load on a disk-shaped metal-piezoceramic bimorph transducer is proposed. Aproblemis formulated based onthe theory of thin two-layer plates. The solution is found using the Laplace transform. By recovering the original function analytically, the problem is reduced to a system of Volterra equations, solved numerically using Tikhonov's regularization algorithm. The finite-element solution of the direct problem is used as input data (potential difference between the electrodes of the piezoceramic layer). The results are analyzed. © 2011 Springer Science+Business Media, Inc. Source

The perspective direction of computer-aided designing of road is optimization algorithms development. Optimization problems solutions can improve the quality of roads projects. Analysis of optimization methods in computer-aided road design system has been shown. These problems solving through the method of flexible bracelet implementation had been suggested. In the article the concept of the geometric implementation of the flexible bracelet method as a method of computer-aided highways designing has been considered. It is advisable to use a rectangle as the flexible bracelet link at this stage of this method development. © 2016 The Authors. Source
