Analysis of the Shape of Stamp on the Distribution of Deformation in the Process of Alternate Pressing and Multiaxial Compression
The paper presents the results of numerical simulations of the alternate indirect extrusion and multiaxial compression process, performed using commercial software designed for the thermomechanical analysis of plastic working processes, Forge 2009. The paper presents selected results on the distribution of deformation in the process of alternating extrusion and multiaxial compression. Examples of modifications to the shape of the die and punch, and their effect on the kinetics of the material flow as well as the likelihood of defects of materials are provided. The results confirm that suitable modifying the shape of the die and punch enables to obtain a material with no internal defects. Iterative process, alternating squeezing and multiaxial compressive strain allows the accumulation of which results in fragmentation of the microstructure.
