Overlapping Surfaces

Altair Forum User

Hello,

 

I am trying to simulate a closed profile bumper beam. I am using HyperMesh with OptiStruct to carry out a linear static analysis.

When I run the analysis, the top surface of beam is going through another surface whereas I want it to engage with it.

Can anyone please suggest a solution for this ?

Hi ayousaf50

 

Can you please check the loads?

 

If the force is high, then displacement will be high.

 

Also, check the stress. If the stress is higher than the yield stress, then please run a material non-linear analysis.

I am trying to simulate a car crash in a static linear option to simply the case.

The stresses that I am getting are a lot higher than the yield strength of the material. 

 

I have tried to run the non-linear cases but I keep on getting an error #1000. I tried to troubleshoot and looked at similar problem on forum but was not able to solve it.

Also, I am not sure about the parameters and properties that I am using in my model, would you be able to assisst me with it ?

 

I have sent the model at the secured dropbox fileshare.

Hi Awais,

 

Please try the drop box link in the signature below.

 

To run a material non-linear analysis you should have material non-linear properties.

I have sent the model to the dropbox link and the material properties that I have are attached in this post.
