How to join honeycomb and skin in ansys apdl for sandwich structure

Click For Summary
SUMMARY

The discussion focuses on joining honeycomb core and face sheets in ANSYS APDL for modeling sandwich structures. The user successfully positioned the face sheet above the core but encountered meshing errors when using SHELL 281 for the skin and SHELL 181 for the honeycomb core. Specifically, issues arose with mid-point nodes not being meshed correctly. The user seeks guidance on selecting the appropriate element for the skin of a honeycomb sandwich beam to resolve these meshing challenges.

PREREQUISITES
  • Familiarity with ANSYS APDL software
  • Understanding of SHELL 281 and SHELL 181 element types
  • Knowledge of sandwich structure modeling techniques
  • Basic skills in finite element analysis (FEA)
NEXT STEPS
  • Research alternative element types for skin in sandwich structures, such as SHELL 99 or SHELL 150
  • Learn about meshing techniques specific to ANSYS APDL
  • Explore best practices for modeling honeycomb structures in ANSYS
  • Investigate troubleshooting methods for meshing errors in ANSYS APDL
USEFUL FOR

Engineers and researchers involved in structural analysis, particularly those working with sandwich structures and finite element modeling in ANSYS APDL.

I modeled honeycomb core and face sheet separately now i want to add or glue them to make a sandwich but it shows error so how can i join them.anyone please

I think you need to give more information?
 
My first problem has been solved i draw face sheet above the core,but when i am using shell 281 for skin and shell 181 for honey comb core which i found best for the purpose the meshing is not achieved in case of shell 281 for skin many errors are coming like mid point nodes cannot be meshed.can anyone pls tell me which element i choose for skin of a honeycomb sandwich beam.its urgent.thanks in advance
