Hello Ahmad

There is a paper that address the parameters necessary to simulate normal strength concrete for the Damage Plasticity model implemented in Abaqus. See the following link.

Hope this helps

Best regards

Pablo , thanks , but is cover only class B50 and im not sure which data  i need for C20 and C40  do CDP represent compression test ? or do i need another model /parameter ?

Ahmad, the plasticity parameters depend on a calibration from experimental results that are described in this paper, but you can find this parameters in other papers. I suggest you try to use first the default values for the plasticity parameters which are  presented in this link http://www.acme.pwr.wroc.pl/repository/338/online.pdf combined with a constitutive model for concrete in compression (Carreira e Chu, for example) and tension which you will take as hardening evolution law (you will input in the compressive and tensile behavior in Abaqus the plastic part of your stress-strain tensile and compressive curves).

Best regards

Dear Pablo , can i have your contact details , viber or whatsapp , please . i can clarify better , the link that you sent is already i got it , but i have to fill in data for compression behavior ´, tensile behavior  and compression damage , i have 6.14 abaqus , i need to do compression test on both C20 and C40 concrete class , i need properties , plaese help , and give me your whatsapp no.

Thanks very much in advance
