Higher stress value

Hello,

 

I have solved my model for FRF (optistruct) , in which i am having localized stress above the yield limit at area of constraint.

 

So, how can i reduce those stresses at the area of constarint (fixing in all DOF), is there any average methode for this or is it ok to have higher stresses at the area of fixing points.

 

Regards,

Divya Sahu

    Do you see any sudden change in stress at constraint location?

     

    can you move the constraint from the current location and check if you observe the same?

     

    It is difficult to answer with limited information, but sometimes you do see high stress at constraints or 1 node near the constraint which is not natural and you can ignore the same.
