How to apply residual stress by odb file
This complete series is game changer!! Thanks a lot men.
I have a problem to connect a rigid wire to 3D wire beam element. I find some tutorial about how to constraint a rigid part to 3D solid. However it seems the prcedure diffrent in 3D wire? I wish if you could just give me some hints or refer me to another vedio? Thank you for shearing!
Thank you sir. It was very helpful.
thank you so much !
Hi Dr. Ahmed, Is there data available for the C & Gama parameters for steel rebar (ASTM) ? Or can these parameters also be used for steel rebar ?
How to make this structure shape...i cant get it
when i edit the keyword as video , it give me this error Unknown keyword "concretefailure". The keyword may be misspelled, obsolete, or invalid. i'm sure of writing so why ?

Thanks for your sharing🥰It is a very useful tutorial. I'd like to ask how can we restart a job use linux command?
How to do the initial settings on Abaqus?, please see the tutorial
Hello Ahmed, can you please make a video for Contacts ie edge to edge contact for abaqus standard, implicit, How to approach?
Amazing video, i have a question Ahmed? How can i do an inclined circular cut extrusion?
great video, thank you
Don't i need to define any interaction of the bolt to the other part?
How to deal it with if we use top diameter instead of angle and different thickness at bottom and top
can we restart jobs ran with user subroutines?
Thank you sir
In case, if we use a strain gauge attached to a coupon sample for measuring the strains directly ,,does this strain is considered as Engineering or true strain ???
strain gauges/extensometers measure strain based on a fixed gauge length (i.e., engineering)
abaqus needs parametric design library for structural elements. Modelling each element one by one is not practical for professional use because most of the time structural engineers have limited time for design/analysis process. I cannot imagine designing a building with abaqus.
Yes. You can also create an abaqus GUI plugin with a section or material library. Some videos available online for the process.
I was a bit confused in the load manager part. Maybe becasue of my own compreenhsion or were there some mistakes in phrasing? found it confusing, if someone could clarify it for me please. I don't know if i should put propagated or fix the bolt lenght.
Thank you very much dear Prof, Can you tell me How do I make Abaqus stop the simulation once a critical value of Strain ot other has been reached? Please . And Thank You again.
In explicit analysis, you can use the *Extreme Element Valur keyword docs.software.vt.edu/abaqusv2022/English/SIMACAEKEYRefMap/simakey-r-extremeelementvalue.htm
@@AElkady Thank you very much Dear Prof. Warm Eid greetings to you and family .
@@AElkady Many thanks Deat Prof .
💚💚💚💚
thank you in advance sir, can i ask for excel data about time summary and acceleration
Is there some way we can modify the interaction in different steps of Abaqus /explicit analysis ??
ruclips.net/video/yfsnBgFBnAs/видео.htmlsi=8Il4NXECpxjfePVO cause u only have time tp 😊
Thank you so much for the tutorial playlist, Dr. Elkady. The videos answered so many questions that I had about running simulations on Abaqus and helped me get acquainted with the controls of the software.
tanks💙
Very helpful. Thanks
thank you from turkiye
How can we do the bolt-pre-tensioning in implicit analysis?
see video #19
Your Video help me so much in my Abaqus project, Great job Dr. Ahmed
Sir can you explain the other methods for pretension where we can't use the static and use the explicit analysis direct. Because in my case i have cyclic loading and can't use the static anlysis also there is increment issues in the static.
Node 2654 instance column-1 has two rigid body reference nodes 3 (assembly) and 2 (assembly). A node may be associated with only one rigid body
It seems you made a double assignment for a reference point. Please check your constraints definitions within the interaction module.
Thanks for abaqus series very helpful
Dear Ahmend, thank you very much for putting this perfect presentation together. I have one question. If I wanted to just export the bolt pre-tension load from standard to explicit without any additional load as you did here, is it possible to do that? Thanks,
It's better to use Abaqus CAD interface (in Abaqus) coupled with Solidworks-Abaqus add-in (in Solidworks). Any change in solid work model will be carried to Abaqus. It's an extremely interactive process.
Sir Ahmad i did like your object but i fond some mastic can tell me what should i do ? the error is (Node 1195 instance column-1 has two rigid body reference nodes 3 (assembly) and 2 (assembly). A node may be associated with only one rigid body)
Sir will this helpful in shear failure of shaer critical beam,i am doing three point test of shaer critical beam and i am geting flexural failure,not shear failure please help me sir
Thanks for detailed summary
Thank you very much
I keep getting error " section must be closed for this type of feature " also, I don't have the option 3D shell only shell in 2D
Your videos are fantastic Dr. Ahmed, I think that you should initiate more list of videos. Can you get a lot a susbcribes because you are god teacher and you have a lot of knowledge. Thank you so much por your learning.
Hi i have a question i put the concrete failure in the edit keywords but it shows error unknown keyword or invalid what should i do here plz help
Thanks a lot for your advices on explicit solver (y).
Congratulations, the concept: Imperfection is very creative because the reality is always imperfection. Thank you so much
Great video! Reggards. Thank you so much.
Me gustaría decírtelo en inglés, o en tu lengua materna, pero lo diré en español la cual es mi lengua materna. Sinceramente eres unos de los pocos exponentes que he visto en internet que tiene la capacidad y la seguridad para enseñar estos conceptos y encima usando un software tan poderoso en FEM como es Abaqus. Desde la distancia te deseo lo mejor en tu vida profesional. Saludos desde Perú.
sir can you make a tutorial about mesoscale model of concrete?
Dr. Ahmed, Can you share a link to download ABAQUS and video to how to install it ?
