Explanation on How to Generate Concrete Damaged Plasticity data from Experimental Result.

[@waheedjaffar786]

Thanks, Mam, You have explained very well, Hope you will continue to upload this type of knowledge sharing videos.

[@waninn]

Most welcome, I will try to make it when I settle other works.

[@basirmce]

Beautifully explained. I'm doing my phd in Australia and read your paper on axial testing of sandwich panel. Learned so much from your work. Please make complete videos on ABAQUS regarding sandwich panel especially your work

[@waninn]

Sure but might not be so soon due to other works on hands.

[@RajuSharma-ir5is]

Very well explained ma'am.

[@waninn]

Thank you so much 🙂

Good afternoon sir, I want to know if the CDP model takes into account the strain rate and if yes would you mind mentioning the formulae? Thank you in advance

[@msc.str.engineermohammedad4269]

thank you so much for your valuable effort , Iam beginner on Abaqus and I need to know how to define CDP parameters to match the experimantal results for an impact load on RC slab ? can you help please ?

[@hamadhasan6487]

Very well explain I would like to after doing compressive test and tensile test how can calculate the crack damage for tensile and the compressive

[@basirmce]

You can use formulas mentioned in videos

Hi madam, if we have 2 material properties, how to assign that in modelling?

[@huuthanhnguyen3910]

Thank you so much

Hi mam if I have only compressive and tensile strength values how can I calculate stress-strain values??

[@johnchen2022]

very good video, thx for the sharing. I have question that how can we get the E at every point on strain-stress curve? cause we know D=1-(E/Eoriginal), in order to get D, we need E and Eoriginal. we have Eoriginal already, but how can we get the E? it seems you can calculate the E from strain-stress curve directly, could you tell me how to do that? thx again.

[@waninn]

Hai, I have explained it in this video. Check it out.Thanks.

[@johnchen2022]

@@waninn thx for your reply, i check the video again, i think you mention the E at 10:00, im pretty sure you said "the E for each part is this ok, for this patches E according to this part", it seems you didnot show how to calculation the E from the strain-stress curve. maybe the E cannot be determined by only strain-stress curve?

[@waninn]

@@johnchen2022 the E is the slope for each points calculated from the stress strain curve based on the experimental data obtained. You can refer to ABAQUS manual for CDP graph which I explained in this video as well for how to calculate the D and E for each points. Thanks.

@@waninn thx a lot

[@safaws918]

Did you calculate E from stresse-strain curve??? How did you calculate E ?

[@SaifulIslam-yh7fn]

Great video. But Madam how can I Determine Dilation Angle, Flow potential eccentricity, Stress invariant ratio and Viscosity parameter?

[@waninn]

Hai Saiful Islam, if you are using normal concrete, you can use the data from previous studies. If you want to determine it from experiment, you need to go thru alot of testing including uniaxial and triaxial compression test. You shall refer to abaqus manual about the parameters. For me, I recommend you to refer to values from previous studies and validate it with your experimental result.

Hi mam, I am a ph.d student, I need guideline to CDP model in ABAQUS. My queries are 1) cube compression test will give single value, ur narration multiple point experimental data. What test to be performed?? 2) similarly in split tension we will get single experimental value. I need your help to complete my work, Hopefully waiting for your reply

[@waninn]

@@boopathyrajapl187 Hai, if you are using UTM machine, it can be obtained from the load and vertical replacement applied from start to softening, just need to do proper set up with prescribed displacement. But, if your machine is not capable to do it, then you need to use strain gauge and get the reading. Hope this explanation is helping you. Good luck!

[@boopathyrajapl187]

@@waninn Thankyou mam. I am doing my research in precast beam erection in NDCT- Natural Draught CoolingTower in Anna University Chennai. For that only I enquired you, if have any doubt in future whether I can ask u mam?

[@johnchen2022]

Hi, man. do you know how to get the E or D on the strain-stress curve?

[@YahyeMohamed]

Thank you , great lecture. Could you please share the files ?

[@hamzadjeffal9240]

If we do not have our proper experiment, generally i use EUROCODE stress-strain relation. Is that okay ?

[@yz5236]

I have the same question here. I dont see any issue with the compression part. It is mainly the tensile stress-strain that we dont have the Eurocode data to support
