The 0.2% Offset Yield Strength Method in Excel Step By Step Tutorial

[@daniell480]

First time I've actually wanted to write a comment about how well done a video is. Thank you very much

[@thePastafarian88]

You are a lifesaver! I have a tensile lab report due tomorrow and completely forgot how to do this.

[@GeneralIVAN894]

bruh same

[@ar0568]

Me, who also has a tensile lab report due tomorrow: :o

[@thedude4619]

Looks like we're all just college students trying to get their lab done lmaoo

[@dndjxnskdbajd4561]

UoB Met&Mat by any chance? 🤣

[@RealDBo]

this lab has taken the life out of me lmaoooo

[@dizoldman3934]

I think your Irish accent helped to make the content of the video even more lucid. Well done indeed.

[@adriennek2050]

nice pfp

[@saminhabibi-luevano1115]

Used this for two of my labs and its a very informative and helpful video. Thanks!

[@TheCompleteGuide1]

Glad it helped! Thanks for watching.

[@Mastermagi01]

I love you you're the best its 5:30am with the lab report due at noon and I was starting to lose hope

😂😂bro you gotta start managing time better

[@jadajeanrizzo6577]

Thank you so much!!!!!!!!!!!! The video was extremely well edited, easy to follow, and very informative. THANK YOU!!!!!!

This video saved my weeks of analysis

本当にありがとうございます! 助かりました♡

[@zainsaeed147]

In your case it was easier to identify the end of liner stage which allowed you to calculate the Youngs modulus and later the 0.2% stress strain. However in case where initially its not clear to identify this linear stage what should we do ??

[@satriodarma1298]

I know maybe is too late to answer but it just feel maybe usefull for other... so anyways, I usualy using a straight line in shape menu and draw the line on the graph for clearly see where the graph is starting "bend"

[@rajsekhardey4510]

Couldn't have found a better video ❤

[@AnnieCali]

you are a god send never stop making videos

[@kas.10th]

why is the column labeled 0.2 % offset stress but you use strain values for it?

[@JustusPanicker]

Strain x young modulus is stress

[@mofipop4641]

This explanation was very straightforward! Thank you so much 😁

[@Joules120]

you saved my as*, thanks!

[@deepakjohsh7748]

Brilliant explanation

[@LoganMurray-vf8gw]

Perfect video, helped out a lot thanks

[@eoincoleman4537]

Thank you so much for this, helped a lot.

[@gabrielsilva6626]

you saved me man, thanks!

[@pragatipatil9308]

Thank you so much for the help :)

[@thabangmoliane5026]

You sir, are the best! 💯

[@miguelbejarano6741]

This only works for metals? or does it work with plastics too?

[@makinemuhendiss96]

how can we find yield strain from yield strength chart

[@Neo-yx3qx]

Thank you so much!!!!!!!!!!!

[@toribenita_kyo]

I came here for help, and I kind of get it and not get it at the same time. Our engineering materials prof is ghosting us and my group and I are left in the dust, not knowing what to do. We couldn't figure what to do with our stress-strain curve. Thanks.

[@zobusasine]

Very helpful thank you

[@giorgos_mark8401]

How do i do this method if i have 60000 values for stress and strain? My graph lines are too thick and i cant see where the 2 lines intersect.

[@angusmcalister593]

hi, same issue. do you have a solution?

[@giorgos_mark8401]

@@angusmcalister593 i had found a way i think by zooming out or i ended up picking less values for the graph i dont remember exactly its been some time till then.

[@konvehdinmussuttaja]

@@angusmcalister593 do you have solution?

[@shayanrahimi7431]

Find the differences between the two curves. Wherever its zero, that is the point of intersection

[@alexfontaine6233]

thanks legend

[@northkangaroos2927]

wouldnt you multiply by 1.002 rather than add 0.002? for 2% offset?

[@alisaain7284]

Harvey brought me here thank you

[@anamelesshobo7868]

How do you do this if you have over a 1000 data entries???

[@Woo-o-e2h]

Thank you !!!

[@dillonjensen2796]

very epic video

[@TizoRami]

My offset keeps deleting my graph can someone help

[@austinwalker5176]

Doesn't work for a strain hardening curve.

[@cokasi4540]

What is YM???

[@krishananushka5]

Thank you.

[@TheCompleteGuide1]

You're welcome!

[@abowden5079]

Something doesn't seem right with this explanation. Doesn't The 0.2% proof stress method involve knowing what the original gauge length is, and calculating 0.2% of that to be your 'addition' to the strain values? I see you're adding 0.002 to your strain values, why 0.002? are you saying your original gauge length was 0.1metres, and so 0.02% of 0.1 metres is 0.002 metres? You should really explain why you're using 0.002 as its not 'always' 0.002.. It depends on the initial gauge length.. Some instruments will measure the elongation with a gauge length of 50mm instead of 100, for e.g.

[@cpatelacademy]

Here video maker is adding strain...not the elongation. It's stress strain curve so the method is right it seems...but my doubt is to take reading when it will cross...manually we need to do that....

[@abowden5079]

@@cpatelacademy Yes, he's increasing the strain value. My point is what you increase it by isn't a constant. It's a variable that is dependent on the measuring tools gauge length. Some people will use a 50mm gauge length, others 100mm, others 200mm, etc. So he should specify why he is increasing his strain value by the amount he is, because it won't be the same for everyone. it seems the video maker doesn't understand it himself, just making a video repeating something he's heard which isn't helpful to anyone who really needs to know how this works in real life.

[@cpatelacademy]

@@abowden5079 no it's not variable

[@abowden5079]

@C Patel Academy then where is 0.002 derived from? What does 0.2% apply to if not the gauge length? Ive used extensometers with 50mm gauge length and ones with 100mm gauge length. It changes the result depending on your initial gauge length. You cant just use 0.002 always.

[@marcup1584]

​@@abowden5079it doesn't matter if your strain gauge is 50mm, 10mm, or whatever. Strain is unitless, or usually nominally given as mm/mm or inch/inch, so it's already normalized as displacement per unit of displacement. In other words, yes, it's okay to ALWAYS add 0.002 (or 0.2% if you're plotting in percent) because strain is already accounted for the extensometer's size when it gives you strain values.
