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!Stress function

      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.
