An analytical model for the heat generation in friction stir welding
The objective of this work is to establish an analytical model for heat generation by friction stir welding (FSW), based on different assumptions of the contact condition between the rotating toolExpand
A local model for the thermomechanical conditions in friction stir welding
The conditions under which the deposition process in friction stir welding is successful are not fully understood. However, it is known that only under specific thermomechanical conditions does aExpand
Material flow in butt friction stir welds in AA2024-T3
The properties of a workpiece joined by friction stir welding (FSW) are directly related to the material flow around the tool. In the present work, the material flow is investigated by traditionalExpand
Thermal modelling of friction stir welding
The objective of the present work is to present the basic elements of the thermal modelling of friction stir welding as well as to clarify some of the uncertainties in the literature regarding theExpand
Two-dimensional mathematical model of a reciprocating room-temperature Active Magnetic Regenerator
Abstract A time-dependent, two-dimensional mathematical model of a reciprocating Active Magnetic Regenerator (AMR) operating at room-temperature has been developed. The model geometry comprises aExpand
Modelling heat flow around tool probe in friction stir welding
Abstract The objective of the present paper is to investigate the effect of including the tool probe in the numerical modelling of three-dimensional heat flow in friction stir welding (FSW). The heatExpand
A WELD MARKER TECHNIQUE FOR FLOW VISUALIZATION IN FRICTION STIR WELDING
Experimental techniques have been developed to allow the investigation of metal flows during friction stir welding. The techniques are based on the use of a marker material that is re-distributedExpand
Thermal models for bobbin tool friction stir welding
Abstract This study presents three thermal 3D models for bobbin tool Friction stir welding (FSW) implemented in Comsol and Matlab. The models use thermal pseudo-mechanical (TPM) heat sources andExpand
