Tensile Stress

Hi;
I'm searching for material Tensile Stress. In material catalog,Is the tensile stress of material engineering values or true values?

Materials do not have the mechanical property of "tensile stress". What they DO have is "tensile strength".

"You see, wire telegraph is like a very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? Radio operates the same way: You send signals here, they receive them there. The only difference is there is no cat." A. Einstein

this is UTS. Uultimate Tensile Stress

Please read "Mechanical Metallurgy" by Dieter and repost a more clear question.Also let us know,for which materials,you are seeking the UTS values.

In Hyperform program, the material have got a true stress-strain curve.but Hyperform library did not have some materials. I search this material values and I found the elongation, tensile and yield strength in catalog. This strength engineering or true ?

thanks

? send the file attachment.

I bet you really need the stress-strain curves for your materials for your Hyperform programme. Yield Strength, UTS, ductility and Young's modulus only roughly delineate that curve and even then you might need some strain rate dependent description.

Yes. I calculate of our material true stress-strain curve for HyperForm. I learn this values is engineering. Thanks for help.
