Description

Shear imbalance is a tooling gremlin that was often ignored until exposed by John Beaumont about 10 years ago. The causes can be subtle but the problems that result are not. In the last few releases, Autodesk has significantly improved the capability for Autodesk Simulation Moldflow software to evaluate shear imbalance. Last year at AU, Beaumont provided an excellent technical presentation on the subject which resulted in those techniques being adopted by 3D Shapes on projects. Evaluating shear imbalance benefited our customers. We hope by highlighting key points for properly evaluating shear rate and and looking at recent examples, we can now help you benefit from these capabilities too.

Key Learnings

  • Properly evaluate shear imbalance effects using a 3D mesh
  • List ways to reduce mesh size and solution time
  • Describe the problems caused by shear imbalance
  • Determine when to use 1D and 3D runner methods
