This note is concerned with the essential part of Finite Element Methods (FEM) approximation error analysis for quasi-Newtonian modelling thixo-viscoplastic (TVP) flow problems. The developed FEM settings thixotropic generalized Navier-Stokes equations based on a constrained monotonicity and continuity coupled system, which cornerstone an efficient monolithic Newton-multigrid solver. manifested...

Abstract This study proposes FEM simulation on forward extrusion of bi-metal rod comprised Aluminum (Core) and Copper (Sleeve). A Deform-2D commercial software with constant shear friction is used to explore the forming characteristics, such as effective stress, strain, velocity field, force, die ratio inner diameter outer at exit after deformation (the aspect ratio). Besides forces obtained by...
