Hello!
Below is a figure of what I am struggling to compare. Standard friction contact defined between plates. 1st load step is preload, 2nd load step is shear load. I am checking dependency of friction change onto how shear load is distributed between bolts and friction at contact. For solid...
Hi Folks,
I understand Ansys solves static problem by following steps (showing just those important to my question, order is important):
1. Material is assigned to elements
2. Shape functions and stiffness matrices are created basing Young's modulus E
3. Calculation of displacements
4...
Hi Folks!
Have you ever been interested in any time management systems? How to schedule your day, week or month better so you can get more things done, etc. And yet I love when it would be simple as for us engineers, we need to have things ready to be applied :)
The one I liked very much is...
Hi all,
Picture below explains the system. I have a solid model with moment load at one side and fixation at other. Two tubes are connected with two bolts to check moment transfer. F2 is obviously larger than F1 due to different levers lengths.
FEA shows high stress at bolt's shaft mainly due...
Hi All,
The question is how to select proper reference stress when weld detail (fatigue category 112) is „starting to be“ the base material detail (fatigue category 140). In other words for what X-position one should use category 140?
Please see the picture:
Hi,
I am looking for a reference in English which would contain formulas required to check following L-Flange connection (please see picture below):
Do you have any and may share?
Regards!
Hi All,
As in subject, I am looking for some book or other good reference which would treat about debugging the FEA. E.g. troubleshooting contacts (or other non-linearity) and solution convergence in general... any kind of debugging guidance document on FEA is welcome.
Regards !
So far I am using Notepad ++ to create my scripts input files. Is there any editor that would be able to show syntax of APDL commands when writing them? And perhaps would be able to auto-finish/propose commands that you start to write?
Example: user writes in editor EMODIF and editor shows him...
Hi Gents,
Please see figure below. I have a shell model, the top part includes mid-side nodes, while bottom part is meshed without mid-side nodes. This is a test model. At the interface between parts there are edges with nodes.
Is there any option to connect those edges in bonded-like manner...
Hi Folks,
What are your best practices to enable efficient parametrization of the geometry in Space-Claim module?
Say, you have created shell model basing polygon with varying radius at length (cone-like), and now you would like to somehow change the radius at the bottom base with one click...
Hi All,
I am looking for a book rather with tables than theory, covering strength of materials such as e.g. some particular section shape with loading and corresponding stress visualization, etc.
Well-known Roark's formulas is an extensive reference but it does not provide practical assistance...

Hi All,
Problem:
One of the most important parameters when setting up the Standard Contact is FKN value (Normal Penalty Stiffness).
FKN controls contact penetration value, thus drastically influencing stresses in neighboring elements.
FKN value is governing, e.g. if one of your plates in...
Hi Folks,
In reference to the figure below, excerpt from EN-1993-1-8:2005:
A - In clause 3.6.1 (2) Gamma M7 is used
B - In clause for Design Slip resistance 3.9.1 (2) there is no safety factor used.
Question: if I am checking Tension of the bolt (not a Design Slip), should I use Gamma M7 as...
Hi All,
Please see picture at the bottom. I have two queries regarding sweep meshing for a nice cylindrical part:
A. How to force orange body to have a nice radial-form mesh?
B. How to force green body to sweep along length without rotation (you may see that mesh is slightly rotated)?
Hello All,
I am FEA Expert in steel, my background is Oil&Gas, Energy and similar industries. I am wondering what mechanical phenomena should I consider to be able to provide reasonable FEA design in your industry.
Thus, I would like to ask my fellow Aeronautic Engineers:
1. What material...
Hi All,
Please see figure below.
Blue and Orange solid steel bodies are bolted with Black beam188 elements. Both ends of the bolt are connected with solids via Red RBE3. Gray plot shows bending moment of the bolt. Bolt is screwed just to some depth in the Orange plate.
Is it good to use for...
Hi Folks,
I have a question on MASS21 keyoption (3).
We can decide whether or not our mass element should include rotary inertia.
So far I always thought that rotaty inertia is always a-must since it lets knows the Solver how unmodelled part behaves under certain acceleration.
My question...
