In Abaqus it is possible to define sets. As far as I am informed you need this sets for creating boundary conditions and defining loads, pressure. What makes me confused is that you can define a set in "Part" and on he other hand in "Assembly", where you find the defined set from the Part...

it is a 2- d model. surface to surface error: max. penetration in some nodes

Thanx for the comments. job completed succesfully by choosing small sliding, but if I choose finite sliding it aborts after 30- 40 % In finite sliding there is no penetration. so how can i fix the problem?

I have forgotten to say that the job completed sucessfully. Do you mean that this penetration is just a visual problem in Abaqus?

in visualization. the rubber edge of body Y deforms and goes through body X while getting in contact.

problem: body X contacts body Y (both iron and rubber on the edge), e.g. rubber on rubber . In visualization it can be seen that body Y go through body X. Contact definition is hard and srface-to-surface. How can I fix this problem? thanx for helping

Thanx. I have already switched to surface to surface. the smooth function helps, but if the smooth-factor is very small, e.g. 0.01 the max. value gets smaller because of the smooth-function.

Problem: a contactproblem between two bodies. After plotting cpress the curves oscillates. I think it has sth. to do with the meshing. with normal meshing the curve looks smooth. But with more finer meshing it looses the smothness. How can I fix this problem in Abaqus (CAE) ? many thnax

Thanx to all comments. I have already fixed the problem by creating a new one with the correct size.

Thanx for the comments. Where can I modify it in CAE Abaqus? There is a "Shetch option" , but I am still confused, because the measurements of the model remain.

As far as I am informed Abaqus does not care about units. After setting the "approximate size" I have noticed that the measurement of the model has the factor 1:100. For example line A to B has the value 1 (distance "H1"). But I want it to be 100. And not only for this line but for the whole...

I want to add an rigid part (plate) to a solid one (cylinder). How can I connect them? thanx in advance

How is the contact pressure (cpress) defined in Abaqus? I am a little bit confused about it. thanx for helping

@tgrimley thank you for the tip. I have ued a distributing coupling surface/ node. But the wished effect is not reached the max. tension has to be top left and not downright :(

Well, I am interested in what happens between femur head and pan.

Many thanx. Concerning the other loads like weight force, i have tried to define it, but the problem is the arc. How can I fix it?

thankx for posting cpomments. first of all i want to consider static case. I have put a sketch in the attachment. Maybe this hepls understanding my problem.http://files.engineering.com/getfile.aspx?folder=b5ad9c19-76a0-4680-8c9d-af9020bfd508&file=hipjoint.jpg

While modeling a 2-d human hip joint I need boundary conditions, One constraint is that the end of the femur is fixed. How can I define this in Abaqus? Do I need a reference point? Many thanx for helping

thank you very much. The next problem is how big are the forces (N/ m2) of the muscles which act omn thr hip joint. I can not find it in google :(

By modelling a human hip joint (cae ansys/ abaqus) i need to consider loads and (bound conditions). One load is the own human weight , which is clear. But which loads do i have to consider too and where do i have to put them in the geometry? Many thanx for helping
