Elastic behavior of metal powders within compaction in Abaqus?

03 March 2014 1 6K Report

For modeling powder compaction, the best model seems to be the "Modified Drucker-Prager (Cap Plasticity)". What model is best suited for elastic behavior of powders? (Between elastic & porous elastic, the porous elastic is for materials containing voids, not powders. So just the elastic model remains. This model also needs Young's modulus & Poisson's ratio to be defined. My question is about how to determine these two elastic parameters?)

Amir Atrian

Young's modulus is a function of relative density which must be defined for ABAQUS using a subroutine (USDFLD)

Is it possible to get ABAQUS/Explicit results (e.g. the nodal displacements) after each increments during solution?

Assume I have an explicit problem with 1 step (which itself has "n" time increments). I need the nodal results after each increments during the solution, not when the solution is completely...
