mean contact pressure static structural
I want to find out the mean contact pressure of two bodies. Below you can see the contact pressure with the display option "averaged".
Below you can see the contact pressure with the display option "unaveraged".
These two solutions are nearly the same, so I think that my mesh is fine enough.
I want to find out the force at which the mean contact pressure is less than 50MPa. So I set Contact Misscellaneous and Nodal Forces to YES at the output controls.
I inserted a force reaction where I choose for Contact Region the contact I am intereseted in. I get following solution:
When I divide the Force reaction of 63809N throug the contact area of 782mm^2 I get 81,6N/mm^2. But when I look at the contact pressure above, I think that that can not be true. In my opinion this is way too high.
You can see my contact definition bellow:
You can see the contact area below:
Can anyone help my the get the mean pressure of my contact or has an idea what I have done wrong?
Thank you an best regards,
