ı am proud of myself. finally ı am reach to watching the Indian teacher's youtube video level.

Finally someone that goes over the theory and a problem.... 10/10

Sir... U R great... One of the best tutorial video I watched on KZread so far....

Thank you, I was in need of this

God bless you, so useful and helpful.... Straight to point and very clear... :)

Thank you very much MY FRIEND!

Thanks so much. The best explanation for this subject Now you will have a follower

Awesome, thank you!

Thank you very much for sharing this video.

Great job bro

YOU ARE A KING SIR

never knew excel can in such a way🛐

thank you very much

Thank you so much. Now if we want to make comparison between the curve from lab result with ABAQUS Stress-Strain result ,should we convert ABAQUS S_S to Engineering ? To Have Lab and ABAQUS S-S in one graph? is it true?

thanks very much

Thank you so much for tutorial. It is very helpful. However what's the notepad used for?

thank you

Thanks

thanks for this great video. I have a question, why did you use 0.000995 as the elastic component? How did you detect that?

I'm working on the detection of springback in v bending in 2D abaqus. But when I define true stress- true strain graphs for plasticty in a few lines in the material definition, the results of the springback are less than the experiment. But if I define only the line where the plastic strain is 0 (the first line (yield point)) the spring-back estimation gets much closer to the experimental results. Is it a correct method to define only the line where the plastic strain is 0? Do you have any other suggestions or is it enough to use this single line?

what we get from ucs test curve we already consider there actual area, (ao/1+e), is it true area, and considering tht what we get is true strain??

I would like to ask that which data points should I enter in FEA software? I have over 400 data points for the compression test of concrete material without any reinforcement. I have converted the raw data by following your video but can't figure out how many data points shall I enter?

HI! Did you found your answer? I am also looking for the same issue!

Sir pls do the video for finding hydrostatic stress of cylinder placed in UTM under upset forging

tx. i have a question? until when we need to enter the data? until fracture point or up to ultimate tensile strenghth?

The point up to which you feed the data will be calculated from the curve and after that the curve is assumed to be straight

Until ultimate tensile strength because that's the point where necking in specimen occurs.

merci, comment déterminer les modules de cisaillement G12.G13. G23. et les modules de young longitudinal et transversale avec le coef de poisson d'un composite sur ABAQUS merci

thank you very much for explaining this problematic. the way I understand it is that, when you display the 3 graphs at the beginning, the first graph is not a stress-strain curve, but a force-strain curve. (because it's just a force divided by a constant area) correct? thanks

damien dambre just plot in logarithmic scale. n will be the slope and k the intercept on the σ-axis

how is used the textpad in abaqus?...i mean why should i use the textpad in abaqus???

Sorry, the way how you are calculating the effective plastic strain is not correct. You have to subtract the elastic strain from the total strain at the specific stress level. The correct way is described here: abaqus-docs.mit.edu/2017/English/SIMACAEGSARefMap/simagsa-c-matdefining.htm

@@aouiched9613 Usually it would not give the same results. This assumption is only correct, if the stress after the Yield point remains constant. This is usually not the case. There are definitely deviations which cannot be ignored.

nice explanation..can I know the name of the faculty.

Hi, if I want do the same with Nylon PA 6 how can I do?.. i'm trying to find data but unfortunatly i can't ... could you help me?

thanks but if you can make video about ductile damage and stress triaxiality it will be a great works

Great suggestion!

the equations are valid until the beginning of necking. You cannot use until fracture.

Sir, how can i start my career as a CAE engineer ?

I am afraid you calculated the plastic strain in a wrong way my friend.. You can review the Abaqus documentation regarding this.. You have to use the true stress at each point.. not only the value at yielding. So it is written like this: True plastic strain = True strain - Elastic strain Here.. the elastic strain does not refer to the constant value at yielding but to the elastic strain that would have taken place if the material maintained the elastic behavior. You can simply write this term as follows: Elastic strain = True stress / Modulus of Elasticity So, basically this term is a variable for each step, not a constant. Please check it here: abaqus-docs.mit.edu/2017/English/SIMACAEGSARefMap/simagsa-c-matdefining.htm#simagsa-c-matdefining__simagsa-c-mat-stress-table

Correct. The true stress is changing every data point and so the corresponding elastic strain is also changing at every data point considered. The E value is constant here. Thank you for pointing it out with appropriate documentation.
