Elongation at Break
Elongation at Break
(OP)
I have two materials
Mat'l 1 Yield = 70300psi
Ultimate = 84800psi
Elongation = 14%
Mat'l 2 Yield = 76500psi
Ultimate = 86000psi
Elongation = 26%
If i substitute Material 2 for material 1, what impact will the higher Elongation have?
Thanks

I love materials science!

I have problems with the results you have:
Mat'l 1 Yield = 70300psi
Ultimate = 84800psi
Elongation = 14%
Mat'l 2 Yield = 76500psi
Ultimate = 86000psi
Elongation = 26%
You have a 14KSI difference between Yield and tensile and 14% elongation.
Mat'l 2 has a 10K Difference and the elongation is twice as much. This is unusual for most materials. The higher the Yield/Tensile ratio is the higher the elongation should be. Have someone check the values again and make sure they use the correct starting Gage length.

GThelen: Are you assuming that the same material is involved here (as in two steels or two copper alloys)?
RE: Elongation at Break
True, did not think 2 different matl's.
