Passage DEM - Discrete Element Method

Powder Forming Process using Passage®/Flow


Step 1 - Compression of Powder
  • Volume change dependent on compressibility of powder and forming pressure
  • Powder move and rotate due to friction
  • Non-uniform stress distribution due to powder movement
Step 2 - Ejection from mold

  • Stress relief and shape spring back

Step 1 - Compression of Powder
Pressure change during the compression
 

Powder Forming Process

Velocity change during the compression

Velocity distribution at a scanning plane

Micro-rotation change during the compression

Micro-rotation distribution at a scanning plane

Step 2 - Ejection from mold

  • calculate the deformed shape on the part due to internal stress using PASSAGE/FLOW software.
