1
I am loading a simply supported beam with different loads but the value of deflection remain same I don't understand why
2.
When I apply tensile load on a structure it some times says "deformation are larger than usual boundary condition so turn on large deflection mode" but I can not find it
So from where I can turn on large deflection switch in workbench .

Open your Model and in Mechanical, Click on Analysis Settings. In the Details Window, you will see Large Deflection under the Solver Controls heading.

If the different loads still give the same deflection after you Solve with Large Deflection On, you can Reply, but after you post, use the Attach button to attach a Workbench Project Archive .wbpz file to the posting.

• thank sir i found it

I have a similar Problem, but i just don`t have the option "large deflection". could you please help me with that? i am using the 18.2 Version of ANSYS

[peteroznewman]

Large Deflection is in the same place in 18.2 as it is in 19.1 but it is only there when you are in an analysis system that allows large deflection.

Some analysis systems are strictly linear, such as Modal or Harmonic Response, and don't allow large deflection so that option is removed from the list of Solver Controls.

Take a look in a Static Structural analysis system to find that option.

Hi all,

problem with large deflection how to resolve it? doing 2d analysis plain stain, material used polyethylene for sqaure and elastomer sample (Mooney Rivlin_5 parameters) for circle.

hi allnI am using static structure analysis but the large deflection doesn't appear at all. help please n

[khaledalazbe]

Even in Static Structural analysis system I couldn't find that optionn

[peteroznewman]

nWhat version of ANSYS are you using?nPlease insert into your reply a screen snapshot of the Details window of the Analysis Settings of a Static Structural model.n
