  1. Pharmaceutical PowderCompaction Presenter: Maxim Rapoport Advisors: Professor: Dr. A. Zavaliangos Grad Student: Adam Procopio http://www.sportmaster.ru/article.php?part=3156 (image source)

  2. INDUSTRIAL APPLICATION Porous Compact Powder

  3. ABAQUS POWDER COMACTION SIMULATION

  4. FINDING CONTACTin non-contactingbodies NO ZOOM 100x ZOOM

  5. PARTICLE DISTANCE How to gauge distance between particles? ?

  6. NORMAL

  7. PROBLEM WITH NORMAL The P1 is a point in particle 1 P2 and P3 are point in particle 3 When normal is calculated P1 is very close to the line given by P2-P3 Contact is detected even though P1 is far from p1-p2 1 RESULT: overestimation at early stages 2 3

  8. COLLISION Before After

  9. RESULTS NORMAL COLLISION

  10. Coordination Number 0 1 2 3 4 5 6 7 Snap shot-Last Stages Normal Collision

  11. Coordination Number 0 1 2 3 4 5 6 7 Snap shot-Early Stages Collision Normal

  12. ANALYSIS • Algorithms converge on late stages • Normal algorithm overestimates the number of contact in early stages • Collision algorithm makes rearrangement apparent

  13. Current Work • Verification of correctness of algorithm • Using contact pairs to evaluate contact area and orientation
