Investigation on the Numerical Simulation for the Dynamic Transition from Liquid to Solid during Liquid-Solid Extruding Forming

Abstract:

The numerical simulation of liquid-solid extruding is completed with ABAQUS code in this paper. The hydrostatic fluid element is used to simulate the deformation of liquid phase and the continuum element is used to the solidified layer. The combination of fluid element and continuum element avoids the mesh distortion of liquid phase during extruding. The dynamic transition from liquid to solid is implemented by sequential coupled thermal-mechanical analysis. One illustrated example of liquid-solid extruding is presented in this paper at last to show the whole modeling process of the dynamic transition from liquid to solid in detail.
