Nonlinear finite element analysis of metal powder die compaction using various plasticity models

Metal powder compaction and its FE analysis have gained enormous attention in the last decade, especially in automotive gear manufacture. However, no specific material model has been accepted as the standard for metal powders. This paper is an effort to study various material models in different geometries. Two case studies were modeled using ABAQUS/EXPLICIT FE package. For both case studies user-subroutine VUMAT was used to implement the …
