I have a concern the stress-strain curve made using a UTM machine differs from the one made using the strain gauges and data logger the reason could be the accounting of global deformation of UTM machine. However, these strain gauges give results usually until the yielding stage and cant capture the post yielding behavior because of large strain. What instrument could we use for this post yield behavior addition to relying on UTM. Also there cant be any correction factor we can calculate and apply to UTM values
First of all we can use an extensometer. Second we can simply take measurement from the displacement ko UTM. Also keep in mind that at the end we only consider the elongation from the central 8 inch portion of an 18-20 inch bar.
40 grade 12 mm bar must bear 40kN load before yielding (this is calculated based on yielding stress that it must bear i.e. 40000 psi) for 60 grade 12 mm bar it must bear 60kN load before yielding.
Yield Strength must not be less than its grade. E.g. for 40 Grade steel it must be greater than 40,000psi (280MPa) Similarly for 60 Grade steel it must be greater than 60,000psi (420MPa)
We are really appreciate you
Sir please share with us this video calculation process
its a good opportunity to learn technical skills...

Sri please description main complete information dain related this machine
Video me bhi to description mojood ha
@@MuhammadBilalZahid its just for digital marketing purpose
Size #4 (67440 PSI ) Perfect result Grade 40👌
Very Good
Brother, very nice explanation. For layman like me, please also tell us that how much load a 12mm 40 grade can bear and also 12mm 60 grade cam bear.
40 grade 12 mm bar must bear 40kN load before yielding (this is calculated based on yielding stress that it must bear i.e. 40000 psi)
for 60 grade 12 mm bar it must bear 60kN load before yielding.
Sir what is the minimum and maximum yield strength accordance to ASTM
Yield Strength must not be less than its grade.
E.g. for 40 Grade steel it must be greater than 40,000psi (280MPa)
Similarly for 60 Grade steel it must be greater than 60,000psi (420MPa)
nice
Boht khob sir
Sir koi kam ki uni ki machine dikha dain plz
Ye aik machine hi bohat sy different kam kr dytyi ha.
@@MuhammadBilalZahid Ap Sir bohat acha kam kar ray hn 🥰
Sir calculation pls
