Good morning

 

I did contact analysis between a cylinder and a plane. The result is below. Note in the image the wrong strain. My questions is how can I improve this?

 

Thanks in advance for assistance.

    Hi Antonio,

     

    Is it plot of plastic strain?

     

    Where are you applying the loads?

     

    From the plot I presume you are apply the loads in the top of the semi elliptical block, is that correct?

    You are checking Displacement plot.In result type change Mag to Z axis and check displacement.

    Default Optistruct would not give strain as output.

    In control card request for STRAIN.Then only you would get strain as output.See attached screenshot.

    Create your 'Load step' and then Card edit. There're OUTPUT options.

    Thank you very much. I did as you said but the wrong deformation remains. I am attaching the wrong strain.

     

    Thanks in advance for assistance.
