FSW Numerical Simulation of Aluminium Plates by SYSWELD - Part II

Abstract

Friction Stir Welding (FSW) is one of the most effective solid state joining processes and has numerous potential applications in many industries. The simulation process can provide the evolution of physicals quantities such as temperature, metallurgical phase proportions, stress and strain which can be easily measured during welding. The numerical modelling requires the modelling of the complex interaction between thermal, metallurgical and mechanical phenomena. The aim of this paper is to describe the thermal-fluid simulation of FSW using the finite element method. In the theoretical part of paper heating is provided by the material flow and contact condition between the tool and the welded material. Thermal-mechanical results from the numerical simulation using SYSWELD are also presented for aluminium alloy.

Process Parameters Optimization for Producing AA6061/TiB2 Composites by Friction Stir Processing

“…The temperatures developed during the FSW and FSP was below the melting point of material to be processed which avoids interfacial reactions and avoids defects like pin hole porosity, air inclusions. The FSW threedimensional model for Al alloy was developed and validated by researchers to build up the qualitative parameters [22,23].…”

The Influence of Material on the Operational Characteristics of Spur Gears Manufactured by the 3D Printing Technology

“…As far as vibrodiagnostics is concerned, it has long occupied the site as one of the most reliable parameters for evaluating the operational behaviour of machine structures. SKF Microlog Analyzer GX was used to collect information on the vibrations (RMS acceleration) of the tested gears [24,26]. A single-axis sensor CMSS 2111 [25,27] was used, which registered the data on the vibration level of the housing of the tested gears in the radial direction and which was positioned in the place indicated in the Fig.…”

Numerical Simulation of Heat Transfer Behavior of Dissimilar AA5052-AA6061 Plates in Fiction Stir Welding: An Experimental Validation

“…In this study a three dimensional thermal model was developed and simulation is made by using commercial FEM code ANSYS. Some numerical simulation works have been done for testifying by some researchers [13][14][15].…”
