Extremely helpful video! Thank you :)
Good video sir
whenever I watch your videos, I always gain some valuable information.
Thank you so much for your clear explanation, Looking forward to seeing future updates.
Sir, Can you share the link for Part-2
Dear,
In channel "SimTech05" - "Abaqus tutorial" playlist - u can find other sequential videos (part-02, 03)
@@simtech0598 thank you for the vedio, I was trying to find part2 but could not see it in your channel, can you please type the link for the video ?
@@simtech0598 i cant find the part 02 and part 3, can you give the links?
Very helpful, thank you! 🤗
Dear,
I suggest to with all videos of playlist "Interaction in Abaqus".
this video is help me thanks
Welcome.
many thanks
Always welcome..
Stay tuned with channel... I'm uploading more.
Thanks for such a piece of fruitfull information. One thing more I want to ask about interactions, is there any option in Abaqus which can automatically detect the contact surfaces and Tied them, in case of many elements.
Yes we have, In general contact algorithms we can define interaction by contact surfaces or automatically.
However, interaction with automatic option computationally more expensive but useful when we don't know which surfaces are going to be interact each other during event.
I'll explain this in next video tutorial also.
@@simtech0598 Thanks, Will wait for the next video.
Sir can you please take a session on errors in abaqus and how to solve them.
Dear Onkar,
There can be many possibilities of errors. So plz let me know what error you are facing.
However, i talked on convergence issue in Abaqus/standard in below videos -
02.3 linear and nonlinear analysis in FEA/CAE
02.4 linear and nonlinear analysis in FEA/CAE
I suggest to go with all videos, many important topic like hourglass and share locking, implicit & explicit, material - geometry- boundary non-linearity..and many more i discussed.
Hello Sir. this is a great explanation of the contact model. I want to place roller support between two surfaces. How can I place this?
Dear,
Apply contact between two surface...and constraint other DOF of objects using boundary conditions.
My project is based on biomedical, in that, I need to check the pullout force of the screw, which is inserted with the bone while taking surgery. considering those things, what kind of interaction is suitable between bone and screw?
Dear,
As threads of the screw consist numbers of surfaces and in contact with bone, I suggest using the general contact there.
Thanks your video is very interesting. But I would like to know how I can model a crack going through two or three composite layers like sandwich structure or masonry wall and what kind of Interaction/Contact should be used.
Dear,
You have to go with Abaqus XFEM. If there is delamination of layers than only you need to worry about contact type between layer.
Otherwise simply define laminate in property..no contact required between laminas.
Thanks but I need to model the crack going from one material to other and in the same time could be delamination exist. Actually I used XFEM technique in both adherend members and also in the adhesive layer between them. And I provided damage failure criteria Maxps in both adherend members and also in the adhesive layer between them. In addition I defined cohesive surfaces as interaction property between the adherends and the adhesive. After completed analysis the crack propagated only in the first adhrend and started in the adhesive layer but didn’t crack it completely and then a lot of cracks generated in the second adherend without any of them completely separated it, so kindly could you please help me to solve it.
hello sir, contact surface can use like crack? I am doing a project like create a crack on edge surface and propagate some wave signal on it.which step tree can be used?
For such crack propagation analysis Abaqus provides separate option by in interactions - XFEM and counter integral.
I not understood what exactly your problem is !
@@simtech0598I want to create a crack on edge surface when I apply tensile load crack should elongate and in compression load should not be overlapped. is it possible to create a model in Abaqus/explicit?
Dear @mani kanta
It is possible with Abaqus/standard itself. No need to go with explicit.
Sir how to define the contact or interaction between brick and mortar while modelling wall element in abaqus
Dear,
You can define cohesive behaviour option in interaction.
sir, i have used skin to represent steel sheet encasing concrete core. do i need to give contact between skin and concrete core? if yes, then which type of contact will be suitable for this?
Dear,
Skin can be connect by reinforcement by both contact method (general contact or surface to surface contact).
Sir, what interaction property should we give while reinforcing element is inserted into the soil?
Dear,
You have to use embedded Interactions.
@@simtech0598 thank you sir
Sir, where do i can find the gap contact element? I want to assign that contact but I can't find it. I'm using ABAQUS 2017 anyway
I have a question. In contact inclusion, is the direction of the mesh important? What's the right direction between 2 surfaces like?
Dear,
For 2D elements and plane stress/strain elements contact direction is important. selection of direction is very easy, you have to select the colour from that direction it touch another component.
@@simtech0598 thank you very much. In other word, the positive or negative direction of 2 nearby mesh part must face each other, right?
I am modelling composite shear wall in abaqus. There is steel sheet with some portion inside the boundary RC frame(75 mm embedded inside beam and column). Which type of interaction or constraint I should use for those portion of steel??
Embedded constraints available in Abaqus. Split it from there it is inside the wall and select only that region for embedded.
@@simtech0598 thank you sir😊
Sir can we draw pressure bulb using abaqus software?
Dear,
I belongs to mechanical, quite unaware to such terms.
However, i can guide conceptually in Abaqus.
could you show us the Gap contact please, Thank yoooou
Yes... I'll try to share some details.
Sir, how to connect two nodes with rigid link for two members, so that force from one member can be shared by others.If anyone knows solution for this,Please help me out.
thanks in advance
Dear,
You need to use coupling constraints.
@@simtech0598 thanku...I'll try!
How to use welded between beam and column in abaqus
Dear, You can use connectors.
can you provide idea about rigid contact element in details
Dear,
Rigid elements are Available in constraints..its stifness is infinite..more u can find in Abaqus documentation. What exact problem u r facing?
Sir how to provide slip property between reinforcement and beam.
Sir I am using general contact normal and tangential behaviour (friction coefficient=.45)but it gives error
Plz let me know clearly what you meant by slip property ?
@@simtech0598 Sir I am working on 3-point bending test on rcc beam.
1) model a RCC simply support beam.
2) reinforcement is embedded in beam than my file is working
3) but I want to provide slip property between reinforcement and beam therefore I am using interaction property normal behaviour, tangential behaviour (friction coefficient=.45) but file gives error.
Sir, if you have time, then I am hard to send my abaqus file to you
Please sir I need your help
Best regards
????
Dear,
In general for RCC you can utilise embedded connection. But as told that you want to define an friction coefficient between reinforcement and metal beams, you should go with manual contact i.e. contact pair/general contact.
However, to do this modelling work will increase. You should make cuts in your reinforcement wherever you have metal bars and contact need to assign.
@@simtech0598 Sir I use surface to surface contact also but strain increment exceeded 50times error is coming.
Sir can I send a .jnl and .cae file to you on
