Stress function over an edge

  Hello everyone,
  
  I have this case study in which I want to test several meshes to this "plate with a hole model". I want to impose a stress state on the boundaries which I obtain by tabular information, but I only managed to impose the normal stress.
  
  Is there a way to impose stress components (X, Y) in the same way using tabular information?
  
  Thanks!

  Hi,
  
  I guess "line pressure" can work as the stress_xx, and pressure can work as stress_yy in your case? (Reference for line pressure: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/wb_sim/ds_Line_Pressure_Loads.html)

  Hello Wenlong,
  
  Thank you very much for your reply, line pressure is a good idea as I need to apply shear stress, but as my problem is 2D I guess I can't use this option. Do you know if there is a way to use it for 2D cases?

  Hi Eugenio,
  
  Yes, line pressure is only available in 3D. The only way I can think of is to do an integration and convert stress to force, then apply nodal force to the top edge. Unlike force, nodal force allows you to define space-dependent magnitude.

  Thank you Wenlong,
  
  At the end, I decided to use a displacement field for this problem as the line pressure is not defined in 2D. But if I will model in 3D, I will use it.
