This article presents two methods to determine pressing forces to the M1 copper plate. The first approach employs the upper-bound method, and the second method combines numerical simulation with a central composite design. The upper-bound method uses physical analysis to determine the deformation zone and establish the division of the rigid block model. The findings were identical to the slip-line solution method.

In this study, we propose to build an equivalent 2D model to replace the 3D model of corrugated composite sheets, by the method of homogenization, to study the nonlinear mechanical behavior of corrugated core composite sheets. This model helps to significantly reduce the calculation time as well as the model building time. The model homogeneity is confirmed by comparing the numerical simulation results of the 2D model and the 3D model.

This paper describes an investigation of fluid flow through two tandem circular cylinders using Lattice-Boltzmann Method in direct numerical simulation. The diameter ratio of two circular cylinders, D1/D2 varies from 0.5 to 1.5, and spacing ratio (L/D2) varies from 1.5 to 10, whereas the Reynolds number of 100 is considered. The numerical model is well validated by comparing the results with those obtained in the literature.

The article presents numerical simulation results for tunnel collapse prediction using the Disctinct Element Method (DEM). The results of the study show that the use of DEM enables simulation of the collapse mechanism and prediction of its potential collapse extent in underground tunnel construction. Based on the simulation results, suitable measures to prevent a possible collapse could be proposed and planned.

A numerical study was carried out to investigate the effectiveness of the charge air cooling method on the exhaust gas emission reduction when applied to a four-stroke marine generator diesel engine at full load. The AVL FIRE 2018a software was used to perform three-dimension (3D) simulations of the combustion process and emission formations inside the engine cylinder operating with various charge air temperatures (CATs).

Ebook "Digital simulation in electrochemistry (Fourth edition)" explains how the partial differential equations (pdes) in electroanalytical chemistry can be solved numerically. It guides the reader through the topic in a very didactic way, by first introducing and discussing the basic equations along with some model systems as test cases systematically. Then it outlines basic numerical approximations for derivatives and techniques for the numerical solution of ordinary differential equations. Finally, more complicated methods for approaching the pdes are derived.
