Hi @Felipe_Mejia , I have a error in this tutorial and some doubts too. Could you please help me to get a solution ?

[@HamOn-ps1ym]

I´ve seen thousands of videos about Ansys, and for sure this is best guy. The quality of the video, the speaking, the way he teaches, the absence of errors (modifying if so), the saving time and of course what he teaches. Everything is perfect. Please do not change anything on further videos. Please more videos about Microplane Model.

[@wangjeerneeful]

Thank you Dr. Dalyo for your useful videos

[@drdalyo]

Nice of you!

[@marcinszyszka7734]

great job, thank you very much for sharing. For your information, I repeated this simulation with version 2023 R1 and the idea provided in tutorial works. Results are however slightly different - in the first phase it is almost identical as Ansys Inc., then, after reaching peak force reaction the softening happens faster (results go belowe experimental curve), however it is still satisfying. I will play later with analysis settings and check the correlation. Thanks once again!

Can you please tell how to bond concrete and steel after assigning material?

[@carelesseagle]

@@abhishekbv8740 If you are using explicit, just use Body Interactions -> Reinforcement. That will assign the contact of the rebar to the concrete. If you are using static structural, highlight all the line bodies in the geometry and change the type to reinforcement. I believe he does this in the video

[@abhishekbv8740]

Sir can you please elaborate as I'm new to ansys and my project is stuck because of this reason please tell me steps to bond concrete with bars

[@carelesseagle]

@@abhishekbv8740 if you look at 3:47 of this video, he changes the model type of the rebar from beam to reinforcement. This model is static structural. If you are using explicit, you would use body-> interactions reinforcement and apply to all bodies

[@alvaroma471]

Thanks for your model, it's really inspiring. I've one question: ¿is this model able to simulate cracking and crushing? It seems that Drucker-Prager concrete is a kind of plastic material since there's not a decrease in its stress when tension strength is reached. What I mean is, is there a way to combine steel reinforcement (via REINF264 elements) with cracking-crushing concrete (via SOLID65 elements with CONCRETE model)? Thanks in advance and br!

[@sreejansree7899]

Very well explained. I tried to recreate the model and managed to run it without any error till 50th iteration. It is showing some error after 50th iteration saying cpu time exceeded. I tried with turing large deflection off and managed to run till 62 iterations. Still I'm able to see partial results. I have some other doubts too. Can we use CPT215 with tetrahedron elements? I saw Drucker-Prager Base model in Engineering data with Uniaxial Compressive and Tensile strength and Biaxial compressive strength. Can we use it instead of the code ?

[@drdalyo]

You can try however i do not believe you can enter the same parameters. And no you cannot use tetrahedral elements
