Analyzing the Dmls-process by a Macroscopic Fe-model
نویسندگان
چکیده
The presented macroscopic FE-model allows to analyze the thermal fields and the resulting stress built up during Selective Laser Sintering. Process and material parameters are focused on Direct Metal Laser Sintering (DMLS). The FE-model is introduced and the assumptions for the model are given. Three different geometric models are discussed. The 3Dmodel shows the sintering of a single line, whereas 2D-models are used for longitudinal and crosscuts of the sintering process. Aim of the investigation is a more basic knowledge about the process, which will lead to a stabilization and optimization of the process.

A “v2-f Based” Macroscopic K-Ε Model for Turbulent Flow through Porous Media
In this paper a new macroscopic k-ε model is developed and validated for turbulent flow through porous media for a wide range of porosities. The morphology of porous media is simulated by a periodic array of square cylinders. In the first step, calculations based on microscopic v2 − f model are conducted using a Galerkin/Least-Squares finite element formulation, employing equalorder bilinear ve...
متن کاملFE-Based Analysis of Hot Forming Process Using the Flow Stress Prediction Model
In hot forming process, the workpiece undergoes plastic deformation at high temperature and the microstructure of the workpiece changes according to the plastic deformation. These changes affect the mechanical properties of workpiece. In order to optimize this process, both the plastic deformation of workpiece and its microstructural changes should be taken into consideration. Since material be...

Electrocoagulation (EC) in a batch cell with Al anode and Fe cathode in monopolar parallel (MP) connection was used for the removal of basic dye, Bromophenol Blue (BPB). The effects of current density, pH, temperature and initial dye concentration, on the process were investigated. Equlibrium data were analyzed using four model equations: Langmuir, Freudlinch, Temkin and Dubinin–Radushkevich. D...

متن کاملManufacturing and Testing Experience with Direct Metal Laser Sintering for Closed Centrifugal Compressor Impellers
Direct Metal Laser Sintering (DMLS) is an additive manufacturing process that utilizes a high-powered laser to build up a metal part by selectively melting thin layers of metal powder. This process is attractive for the manufacturing of parts with complex geometry such as closed centrifugal compressor impellers. DMLS allows closed impellers to be made in a single piece and eliminates the shroud...
