The non-asymmetric rolling process of copper and brass wire has been simulated with the Abaqus software. Presented finite element model in this simulation of rolling predicted output curvature and contact surface width in the non-asymmetric mode (in equality of diameter of rollers, the rotational speed of the rollers and the rollers’ surface finish). The material used in this research has strai...

In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...

Simulation data have been presented on a process of deep refinement tellurium based Authors-developed technique implemented through analysis the unit thermodynamical condition using Flow software, from SolidWorks software product. The put forward herein has in plant comprising vertical air-tight reaction chamber arranged inside multi-zone thermal and executing sequence stages which use differen...

In this study the operations of melting of Au15Ag40 nanoalloy have been studied using the molecular dynamic simulations through the Gupta multiparticle potential and the nonergodicity of simulations is eliminated by the multiple histogram method. The melting characteristics are determined by the analysis of variations in the potential energy. The calculations indicate that the melting of Au15Ag...

Many researchers content themselves with the 2D simulation of welding process instead of the 3D simulation, because of the time and the cost factors of the latter. In this research, the number of elements and nodes are reduced by an initiative plan (defining an equivalent model) for the simulation of welding. The welding process has been simulated by an uncoupled thermal-mechanical finite eleme...

abstract: in this paper, the results of experimental and numerical simulation of low velocity impact process have been carried out to investigate energy absorption of composite sandwich panels with 3d woven fabrics of glass fibers and epoxy resin. for this purpose, diagrams of force-displacement of the quasi-static and quasi-dynamic impact tests were studied. for the finite element simulation, ...

Laguerre function has many advantages such as good approximation capability for different systems, low computational complexity and the facility of on-line parameter identification. Therefore, it is widely adopted for complex industrial process control. In this work, Laguerre function based adaptive model predictive control algorithm (AMPC) was implemented to control continuous stirred tank rea...

This paper presents an overview of how business process modelling and simulation can be used together. In particular the development of a prototype tool that automatically generates simulation models from process models is illustrated. We describe the process of the development of the prototype, the diierent models involved, Role Activity Diagrams and Discrete Event Simulation and the mapping o...
