asymmetrical analysis with contact

[edoardo copertaro]

hello to all, use ansys 11 for a stamping simulation. I am looking for an asymmetrical element, which supports contact and plasticity. I tried with 183, but refuses any model of non-linear material. Does anyone have any idea what element to use? ?

Thank you.

plane183 is fine.
read more Good ansys guide and you will see that in the first 3 rows it is written that supports stress-deformation states of type plane stress - plane strain - axialsimmetry and has all kinds of nonlinearity.
Remember that the contact is independent of the "structural" elements and is managed with other elements (conta172 - targe169).

you had read the element guide. ..but when I tried to launch the solution it gave me as an error message that the model of material used (elastic multilinear, i.e. interpolation of the traction curve ) was not supported by the element...now I went trying with plane 42 and does not give problems, but the results remain different from the theoretical ones....we hope to solve
