Your videos are quite helpful. Can you please make a video tutorial in which plain concrete cube is made and instead of defining concrete as one material, we use cement ..sand and aggregateor any other composite etc... my aim to learn how to model calorimetry of cement..and further work on thermal propties of mass concrete.. thanks and regards

What are the plastic properties? Dilation angle,,,, etc,,, Is it different from normal concrete?

[@vitukoconnection9935]

There is no need to use plastic strain?

Please tell me how to model bond slippage between bars and concrete in abaqus?

[@hnrwagner]

cant say never done it

[@mito8096]

thank you for this amaizing video, but do you have a video of how to simulate a beam under torsion or a video to describe how you built the torsion model in the video here. thank you a lot

thank you very very much it is ok and give good result

good to hear :)

[@sohailhamza2812]

Hi from did you calculate stress-strain values or are those experimental results??

[@FreelancerIbrahimik]

Can you explain that how do you write stress and strain data ?. Is this data calculation here any relation to yield stress?

[@ephremmohammed2107]

how can I create for 70? because it is difficult to get the ultimate strain.

[@ephremmohammed2107]

how can I generate the stress-strain history for M70 .(the difficult thing here is getting the ultimate strain for M70) please help me?

[@rafattahzeeb7762]

concretedamagedplasticity.com/ Above is the link to calculate the required parameters. Its a webtool developed to calculate mechanical property of concrete upto grade M100

[@yousefabuamneh6620]

The values of stress and stress highlighted in yellow are elastic?? How did you confirm that those linear elastic?

[@hnrwagner]

They are below yield stress?

[@yousefabuamneh6620]

@@hnrwagner Yes, the ones higlighted in yellow, with max. 62 MPa stress, did you assume the max. linear elastic strength = 62 MPa

[@yousefabuamneh6620]

@@hnrwagner In other words: The 0.45 fc does not apply in UHPC?? as a max, linear elastic strength?

[@hnrwagner]

@@yousefabuamneh6620 i am not sure, what do you mean? Do you perform a similar analysis using concrete and the cdp material model? There are a lot of videos on my KZbin channel covering this topic

Insightful tutorial. This method can calculate & become input for steel fiber concrete in abaqus. Correct me if I am wrong. Thank you

internal pressure oder external pressure?

Can you please send the link or the name of paper for UHPC material ( CDP) that you used in this video

[@hnrwagner]

The data was send to me via email, no reference given

[@ahmedsamir787]

excuse me, the last question, in the ultra high concrete with out fiber not have post-peak behavior ( no strain after peak strength ) as shown in attached picture in research gate how make CDP for it ?

[@ahmedsamir787]

when remove the values after peak stress the result of abaqus is not good

[@hnrwagner]

@@ahmedsamir787 i will take a look at it, but i think then you have to choose a dífferent material model

Hi Sir, Thanks for your amazing video tutorial. But you may calculate compressive part . Can you calculate and make video for tensile damage parameter for abaqus ?
