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...

How can define "initial relative density" of powder through modeling powder compaction in ABAQUS using Drucker-Prager Cap (DPC) model?

Is it possible to define initial density for powder compaction in ABAQUS using DPC material model? I couldn't find about this. I think the compaction behavior will differ with different initial...

How to make a shock wave in solids with impact?

As known, a shock wave is induced when the plastic stress wave becomes faster than the elastic one. Can anybody suggest to me how it's possible to make shock waves in metals like steel using an...

How can I etch Al7075 to view grain boundaries?

I used some etchants like keller and kroll, but I didn't get any results. Is there any chemical solution for this or must I use electroetching?
