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...
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: drive.google.com/drive/folders/1fY0oU2huGU4ghHtP6MEe9AIGX5P_lgm_?usp=sharing
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? :)
Hi Rashid Karim! I would strongly encourage you to refer to the lecture series: MIT OpenCourseWare ua-cam.com/video/oNqSzzycRhw/v-deo.html Michigan Univ ua-cam.com/video/U65GK1vVw4o/v-deo.html IIT Kanpur ua-cam.com/video/UOp6JEiJctA/v-deo.html
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
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: eprints.kfupm.edu.sa/id/eprint/140047/1/MS_Thesis_of_Hamdi_A._Al-Sakkaf.pdf
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
@@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?
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?
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 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 ?
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.
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.
@@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.

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.
Sir plz reply how you take the depth of the support..
Depends upon your experimental setup.
