The limitation of resources, i.e. materials and energy, linked with increasing prices forces enterprises to operate economically with their material and energy consumption. But many companies, as experience shows, are not able to take action as they are unaware of ways to identify efficiency potentials within their production processes. This applies primarily to small and medium enterprises, wh...

in this study, the effects of linear and rotational speed of the friction stir welding tool was investigated on the heat generation and distribution at surface and inside of workpiece, material flow and geometry of the welding area of poly methyl methacrylate (pmma) workpiece. the commercial cfd fluent 6.4 software was used to simulation of the process with computational fluid dynamic technique...

This article examines options of an innovative design of intralogistic systems by interfacing small-scaled modules. Current intralogistic systems are quite customized with unique solutions and small production lots. In most cases these systems feature a central main control. To offer highly individual solutions, thus meeting the demand of shorter life cycles, there is a need for more flexible m...

In the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. In this study, a series of compression tests were simulated using Abaqus software. In this study, it has been employed the Taguchi method to design experiments by the factor...

The objective of this study was to develop a numerical model for the prediction of temperature distribution, effective plastic strain distribution, and especially material flow in friction stir welding of copper plates. The DEFORM-3D software was used by incorporating a lagrangian incremental formulation. Threedimensional results of the material flow pattern which were extracted using the po...
