Dear all,

I am trying to simulate the load on a 2D fixed curved beam. In adding the loads, I am adding a vertex, or line load. I wondered, how can I add the load on a rigid surface, so that my simulation is not dependent on the surface where the load is added. ABAQUS has something that is called Analytical Rigid Surface. Does ANSYS have anything like that?

Is the only reason for the quarter circle in the corner to create an edge to distribute the force to avoid a high stress that was seen when the load was applied to the vertex?

The problem you introduced by making the edge was the force moved away from the vertex.  You can overcome that problem by using a Remote Force. In that way, you can have a separate definition of an edge to distribute the load and the location in space of the point of application.

If you use a Remote Force, you don't even need the quarter circle. You could just select the vertical edge of the 2D part and position the point at the vertex.

Yes and no.  Depending on the strain energy results, I will make partitions and add materials with higher modulus of elasticity (the region where the load is located included). I was just trying to know whether I can make that line rigid (not deform) and apply the load in the rigid line. Abaqus seems to have Analytical Rigid surface, so the load is applied to rigid surface, and is not depended in a node.

The shift of the force from the vertex is not a problem at the moment.

Hi,

As Peter mentioned, remote force can do the job, but you will need to set the "behavior" of "remote force" to "rigid". That way, it is treating the edge as a rigid line. Please refer to this site for detailed information about remote force and its behavior: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/wb_sim/ds_Geometry_Behavior.html.

Dear Wenlong,

Thank you for your reply. It seems I cannot access the link you provided,  due to using a student edition of ANSYS. Is there any way to access it?

Sincerely,

Astrit

Nevermind, I found access through the useful links. Sorry

Dear peteroznewman and wenlong,

Before completing this post as solve, I just have one more question. Is this rigid remote force distributed along the line?

Sincerely,

Astrit

Yes it is.
