Thanks for your answers.
Could you explain why is it so important to exclude the bending stress component parallel to the classification line. Isn't it conservative to include all of the components? or what is the reason behind it?
I tried to verify myself, not sure how good it is (I did calculate by components first :) )
It seems to me and at least for this example that ansys is not doing that bad?http://files.engineering.com/getfile.aspx?folder=443b272a-63d7-464c-a360-2cc7d4a6db9a&file=linearization_check.xls
Actually, You wrote that the "default linearization scheme in ANSYS is not compliant", so I was hoping it could become compliant with specific settings, but maybe I misunderstood.
Could it become compliant by using “axisymmetric straight” as 2D behavior with “through thickness bending stress” ignore for the non-axisymmetric (due to bolts) 3 D model , as it is mentioned in the help : “These choices are available to any type of geometry (for example, you can choose...
I looked to ANSYS help, but it did not make it clearer especially about the "2D Behavior".
I wish to "Ignore the thickness-direction bending stresses" but for that I should use "Axisymmetric Straight", which I do not clearly understand. Could you help me on that?
Thanks
look at those commands :
*dim to create a array parameter
*vget to retrieve values and stores them in a array parameter
*do (do loop )
*get to get the loc z for each node of the table
*endo
and then find the max
or directly
NSEL,S,LOC,Z,-0.2
*GET, Parameter_name , node , 0, mxloc, z...
With the pure penalty method, the contact force is : F=k*xpenetration
k is the normal contact stiffness.
A large value of k gives less penetration, but the model can oscillate and you have convergence difficulties.
If the value is too small, there is too much penetration.
You have too try...
to draw, use 'chart and table' :
'Selecting the Chart and Table icon button allows you to create charts of loads and/or results against time. In addition you can also chart result quantities against a load or another results quantity.'

Have you already tried the contact stabilization ?
'For standard contact (KEYOPT(12) = 0) or rough contact (KEYOPT(12) = 1), you can use real constants FDMN and FDMT to define contact damping scaling factors along contact normal and tangential directions. The primary goal of this contact...
