Sensitivity Analysis of Laser Drawing Process of Mg tubes

Popis výsledku v původním jazyce

Although magnesium alloys are widely used in the industry they suffer from low ductility at room temperature which causes technological difficulties. New production processes need to be developed mainly for small elements like tubes of small dimensions. This contribution aims to a novel production technology based on laser dieless drawing process in which tubes (AZ31 alloy) are produced from previously extruded tubes of a~larger diameter. The technological process involves local laser heating of a tube with concurrent drawing and rotation of a~sample. However, the process is relatively sensitive and the setting of material parameters as well as the varying control parameters like drawing speed on tube ends, laser power or torque play a~substantial role. In this contribution, the sensitivity of material models' parameters are evaluated and their influence on the resulting output from FEM analysis is evaluated.
