Hi guys,
can anyone explain to me why the stresses calculated in Expicit are greater than the ones in Standard when doing a quasistatix analysis? Is it because the mass is taken into regard?
Thanx,

Hi guys,
can anyone explain to me how to restart an explicit-analysis? What I do is:
-take the original Input file with all the steps and loads, upload it into CAE
-then go to load module, and input in the field dialog box an initial state from the aborted calculation
-then write a new input...
Hi guys,
I'm having big time trouble analysing a soft layer being pessed together by two hard parts (contact) and then the upper part being traccioned to one side, so that friccion forces act between the layers.
The problem is, that there are up to 1000 eigenvalues and the soft layer elements...
Hi guys,
I've got a problem understanding my Abaqus Explicit results. I apply on one face of my part a dicplacement condition, say 50 mm and let that step run in Explicit. In the contour plot at the end of the step, I print the output for the displacement in that same direction at that same...
Hey everybody,
I'm trying to model gasket material (FEM) but don't know, it's properties. Can anyone help me out on that and give me at least some "out of experience"-values?
What I know about the material is that its an elastomer (NBR) filled with carbon fibers, which are oriented as a result...
Hi guys,
I've read already quite a lot on how to avoid Negative Eigenvalues in contact problems and tried to consider all the advices in my simulation but this problem still occurs.
What I do is put a normal load on one piece in one step and then apply a traction load. The eigenvalue - problem...
I'll try my question in a separate thread, maybe anyone can anwer it.
I read abaqus documentation a couple of times now, but haven't quite gotten it wether to use hybrid elements for an elastomeric material or rather reduced integration elements. The material is subjected to shear forces, would...
Hi guys,
I've got a question on something I noticed after doing a calculation. When I look at the results in the contour plot at one location one element displays entirely different than the surrounding ones.
To make myself clearer: I have calculated a contact problem with friction. Then the...
I'm having a big problem with the convergence of my contact model. Every calculation is aborted with the note "too many attepts", what can I change to either to let more attempts be made or ....well I don't know. What can I do????
Hey everybody!
I've got the following question:
I'm working with ABAQUS CAE or the python scripting and would like to define node sets in the way that I say: the node set includes all nodes that are having the z-Coordinate equal to 10. I also would like to give another number to the nodes than...
I get the following error message:
IT IS NOT POSSIBLE TO ESTIMATE THE TOTAL AMOUNT OF MEMORY THAT WILL BE REQUIRED. PLEASE INCREASE THE VALUE OF PRE_MEMORY
CAn anybode tellme what to do???
thanx a lot!!
HI!
Please help!
I have created a model of 3 pieces (deformable solids) lying one above the other. And defined contact interaction (tangential and normal)between them. The undermost solid is restricted by "encastre". Now I would like to put a load on the top of the uppermost surface. But at...
Since I decided to use Python, I'm having the next problem now:
I'm havind to parts, that I want to be lying one above the other. How can I input it a Python skript? Is there some het-command that would give me out the center-coordinates of a cube face? Or can I somehow position a reference...
I´m just a beginner with abaqus and therefor I'm having a big question for the start.
What should I work with creating a model. Should I rather write a python or rather an .inp-file. What are the advantages of these both posibilities.
I've got the impression that the majority of users prefers...
