A three-dimensional elasticity analysis of bi-directional FG square plate subjected to mechanical loadings is investigated. The material properties are assumed to be graded in the thickness and longitudinal direction, which vary according to the simple power law distribution. The equations of equilibrium and the related boundary conditions are derived using the three-dimensional elasticity theory. Differential quadrature method (DQM) as an efficient and accurate numerical tool is adopted to solve the equilibrium equations. The accuracy of the method is demonstrated by comparing the results with those of the existing solutions. It should be mentioned that results for three-dimensional elasticity analyses of the FG and bi-directional FG square plate subjected to mechanical loadings by differential quadrature method are not available yet and the results can be used as benchmarks for the future works.

In modern science, computer analyses and simulations represent an essential part in the creation and design of mechatronic systems. This paper discusses a newly-designed virtual model of an electronic differential lock (EDS - Electronic Differential System) which consists of mechanical parts created in MSC.ADAMS/View simulation environment and a regulatory scheme designed in MATLAB/Simulink. The two interlinking programs form the base for a mechatronic model evaluation based on various driving conditions.

The paper presents an analysis of a floating structure response to underwater shock loading. An explicit finite element approach is used for the shock fluid-structure interaction. The floating structure modeled in this study is a scaled 3D ship. Underwater effects such as shock wave, bubble, cavitation and acceleration are considered. At the first part of this study, the model is checked with various experimental and theoretical results such as modal test results and peak pressures. After validation of the created model, the effects of shock wave, bubble and cavitation are investigated. This study shows that the shock factor can be used as a criterion of shock severity.
