Converting Engineering to True stress-strain curve Tutorial

This video describes on how to convert Engineering stress – strain curve to True stress-strain curve. For FE model for accounting material non-linearity we need to feed True stress-strain curve with minor modification to effective plastic strain. Formulas for conversion along with Excel sheet use has been demonstrated to carry out this exercise quick error free and this video also shows copying this data to AbaqusCAE window and editing input Textpad file.

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

[hiltoncosta]

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

[eliassaf]

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

[akshatb]

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

[KunleAdeyemo-iity]

Thanks for the explanation but the effective Plastic true strain formula seems not really accurate. Although approximately the result are the same but when there are data, the deviation might be obvious

[amrounesalah]

Thank you very much for sharing this video.

[MohamedShafiq-eq]

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

[arthurjohnson]

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

[dwiedinne]

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:

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

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?

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

[JackSparrow-ytqw]

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?

[lucivalmalcher]

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

[baishalinandi]

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??

[hoseinreyhani]

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?

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

[hitzz]

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

[UppadaRamakanth]

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

[aouiched]

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