Applying Load on an area - ANSYS APDL

Click For Summary
SUMMARY

This discussion focuses on applying loads to an area using ANSYS APDL, specifically with Solid-Shell elements and the SURF154 element. The user encountered difficulties in applying a 250,000N force and sought assistance. A solution was provided, referencing the ANSYS help documentation under "Mechanical APDL" for commands related to surface loads, including SFA, SFALIST, SFADELE, and SFGRAD. The user ultimately resolved the issue by applying a negative pressure instead of a direct force.

PREREQUISITES
  • Familiarity with ANSYS APDL and its interface
  • Understanding of Solid-Shell elements and their applications
  • Knowledge of surface load application methods in finite element analysis
  • Basic concepts of pressure and force in mechanical simulations
NEXT STEPS
  • Review the ANSYS APDL "Basic Analysis Guide" for detailed loading procedures
  • Explore the commands SFA, SFALIST, SFADELE, and SFGRAD for applying surface loads
  • Investigate tutorials on Solid-Shell elements in ANSYS for enhanced modeling techniques
  • Learn about pressure application methods in ANSYS for alternative loading strategies
USEFUL FOR

Mechanical engineers, simulation analysts, and anyone working with ANSYS APDL who needs to apply loads effectively in finite element models.

Hi,

Have been using ANSYS Mechanical to conduct some analyses, but am now moving to ANSYS APDL to investigate the effectiveness of Solid-Shell elements.

However, I've run into a problem. I can't figure out how to apply a load to an area!

I have been playing around with the SURF154 element (as i have a 3D model) but can't see where to apply the 250,000N force required.

Have tried seaching the web for tutorials, but no luck :( Does anyone know how to do this?

Any help is much appreciated
Many Thanks

Did you look through the ANSYS help?

Specifically under "Mechanical APDL" / "Basic Analysis Guide" / "2. Loading" / "2.5 Applying Loads" / "2.5.7 Surface Loads", Table 2.6: Commands for Applying Surface Loads.

Commands for applying surface loads to areas include SFA, SFALIST, SFADELE, SFGRAD
 
Ahh right, no didnt see that. I got around the problem by applying a negative pressure (as I knew the area the force was being applied over) on the surface.

Thanks for the comment though!
