Thank you sir for this video, its real helpful for beginners like me. i will send you in your email my other questions.
Very useful 👌
Congratulations on the video! It helped me a lot!
Sir, what was the compression damage model used?
Hi Marcilio!
The damage model used is Mark & Birtel 2006.
@@BoldLearning Thanks!
Amazing 👍
It is really helpful. Can you please let me know if I have to model a plain concrete cylinder and I want to work on grain sizeand incorporate sand, aggregates , cement or any other material etc properties... i want to see thermal behavior of concrete composite at grain level...is it possible?? If so I would request to upload a video clip...
Very useful
Thank you
I want to learn abacus software related to my research work
Is it possible to do a tutorial on the method of defining concrete by using concrete smeared cracking method
Hi sir
The CDPM model described is very informative. My doubt is that how it is decided at what values to get the data for the compression and tension behavior of concrete.
Hi Harkirat!
Thank you for the great feedback!
The data can either be taken from experiment (if available) or from any available concrete stress-strain relationship models (such as Kent and Park, Scott et al, Mander models etc.)
You may refer to this excel file for data for some grades of concrete along with concrete and damage models:

Bro what is the total load you applied
Is it 10KN or 10N
Or 20KN (In total)
Nice vedio bro helped me a lot
God bless you
Hi!
It is displacement-controlled.
A displacement of 10mm is applied.
HI, great video!
Im doing an uniaxial test of a concrete beam without reinforcement to validate my material model. Apparently Im calculating the inelastic strain and damage parameters wrong.. Is it possible to see your excel sheet to see what formulas you are using? :)
Which constitutive model for defining the tensile stress-strain and tensile damage of concrete, you have used? Thanks is advance.

Sir plz reply how you take the depth of the support..
Depends upon your experimental setup.
can i have the exele sheet for calculate the concrete damege
Can you please post a tutorial on Ferrocement beam
Sir how to provide local damage to beam.
Sir you makes very good videos
Keep going.
Thank you for the feedback!
You can define damage of concrete in Material Definition...
In "Plastic" >> "Concrete Damage Plasticity" >> "Compressive Behavior"...Open suboptions>> "Tension Damafe" ...Then enter damage for corresponding strains
@@BoldLearningsir can you provide some value for M30 grade concrete
@@BoldLearning sir I use your value which is provided in video but when I try these value than my file give error compression damage value negative or decreasing.
Sir how to solve these error?
@@navdeetsaini5553 Sure...Email me at boldstrokeschannel@gmail.com
@@BoldLearningSir check your email
sir how, I provide smeared cracking in abaqus and how to get that values ?? can you help me in this regard please !!!
sir what is unit of load? did you appiled on beam?
Concentrated load in N

@Bold Learning can you please post a tutorial video on Finite Element Analysis
Hi Rashid Karim!
I would strongly encourage you to refer to the lecture series:

Great work. Please can you make video about uniaxial compression test of cylinder (50 mm * 100 mm) consist of soilcrete ( sandy soil improved with cement ) which is plasticity behavior based on Mohr Coloumn law which subjected to displacement controlling loading with velocity 1mm/min. Thank you very much
Hi Bold learning
Can you plz give me the concrete damage data or the excel file
Thanks for this informative video, Sir Can you explain on how to add property of Steel Corrosion while modelling the RCC Beam?
The best way to model corroded steel in RCC structures is to use surface-based mechanical contact or surface-based cohesive behavior.
This thesis might help:

Hi there, thanks for your efforts
can you please send me the excel file used for the concrete parameters . and what paper you used as a reference here ?
Hi there, I already input compression/tension data in concrete material but the damagec/damaget output in field output request does not show up. what should i do?
Have you experienced a problem during the results/post-processing where the loading plates are displaced into the beam and without the beam carrying the load. I ran through defining the model two separate times exactly how it was done in the video but I am still experiencing this problem.
Hi Tyler!
You can easily overcome this issue by enforcing a "Tie" constraint between the surfaces.
Alternatively, you can assign a "hard contact" between the surface while defining interaction.
@@BoldLearning I had defined 4 total tie conditions per your video (left support plate, right support plate, left loading plate, and right loading plate) and still am experiencing the issue. When going into interactions within the initial and loading step, I do not see an option to assign a hard contact, only "general contact", "surface-to-surface contact", and "self-contact." Thanks.
Tyler Dennis
Hi Tyler
If assigned perfectly you will likely not run into this issue.
Make sure you create a tie with master surface as steel plate face and slave surface as the corresponding concrete face.
thank you for this tutorial video , after the job is completed i didn't get the damage results and the legend of damageT and damageC just show zeros ? can you tell me what should i do ?
Hi Ali!
Please make you have entered the damage parameters in the damage suboption while definig concrete
@@BoldLearning yes i am sure i did ,but it still schows zeros , also the cracks didn't apear at all in the beam
@@BoldLearning another point : what if i use the static general in the step? it can make any difference ??
It's great vidio.
Do you have material properties for mortar
Thank Syah!
This paper might help: www.hindawi.com/journals/mse/2020/1676190/
@@BoldLearning thank so much
I've chacked the papers, but i dont found the parameter inputs for mortar in analysis using abaqus. Could you help me to find it?
Are the values entered for concrete damage plasticity experimentally derived?
Hi Sidharth!
No it wasn't.
The concrete compression stress-strain plot was developed based on the Scott et al (or Modified Kent and Park) Model (1982).
The concrete tension stress-strain plot was developed based on Wahalathantri (2011) and tension damage based on Birtel and Mark (2006).
The plasticity parameters chosen are the default values given in the ABAQUS Documentaion.
Thank you Sir for the video. How to obtain load carrying capacity of the beam?
@@ridhosurahman8461 Hi Mr. Ridho!
Take a look at 20:08 . Steps for data extraction for load vs displcement is given. Load is extracted using the variable reaction force (RF2) and displacement (U2).
I hope it's clear.
@@BoldLearning Hi sir,
1- Did you convert the compressive stress-strain curve that you obtained form experiments to True stress-strain curve?
2- In the steel defining material, you did not define the plastic behaviour of the steel from Suboption, as you did in concrete?
Is that okay for me to ignore the plastic behaviour for steel as you did?
Thanks a lot for the useful video, it's very helpful for beginners like me to build a CDP mode.
Hi @@mohammedalsidran9773 !
Thank you for the feedback!
1. Constitutive relationship of steel: The model has assumed ideal behavior (theoretical, i.e. elastic-perfectly plastic)
2. Plastic property: Plastic property is considered. It is assigned by "Plastic" option in Material properties.
Is there any Excel sheet link sir???? Thankyou in advanced
Do you know why i don't get the DAMAGE options in the results?
did u request it in field output
Hi Abbas
You have to activate “DAMAGET” and “DAMAGEC” in the under the Failure option in the Field output
Hello sir
What is meam DAMAGET
Example 0.8
Hello bro
I downloaded your files in Google Drive but I didn't know which paper you followed it in your video
Hi @The Engineer
The model created is an example. The files in link gives some input data for various concrete strengths and some concrete stress-strain models
@@BoldLearning thank you for your answer, I want ask you about your file (CDC_KT) can I know which paper that you take from it because I need the parameters for high strength concrete with it paper please,
thank you, please can you share with us the excel file ?
Could you please send me xls file if you don't mind?
Why i not get damage menu?
Hi fiqi!
Please go to:
* To input compression damage data:
"Materials" -> "Mechanical" -> "Plasticity" -> "Concrete Damage Plasticity" -> "Compressive behavior" tab -> suboptions : "Compression Damage"
*To input tension damage data:
"Materials" -> "Mechanical" -> "Plasticity" -> "Concrete Damage Plasticity" -> "Tension behavior" tab -> suboptions : "Tension Damage"
