From Tensile stiffness to young modulus 1

[frztrb]

Hello all

I have a technical table that in it , the tensile stiffness is give , but I need the young modulus , how can I arrive to young modulus E from this information ?

sorry if it's basic

I never heard of tensile stiffness - what specifically materials are you looking for the Youngs modulus?

OK, I just googled this - maybe the 2 are the same.

tensile stiffness may be AE/L ?

yes , tensile stiffness is AE/L , and I need it for a cardboard

 

[rb1957]

so if they're telling you (AE/L) then they should be saying something like "for a piece so big (ie A and L)".

you could ask the manufacturer what they really mean, and how they determined it; personally i'd do a tension test.

Frztrb:
It seem to me that you would do well to get a good Strength of Materials text book and review these concepts so you have a vague idea what you are doing and asking. These are actually fairly sophisticated concepts and material properties, and may not even be directly applicable to your problem. With questions like these, you could really use a local mentor to help you formulate your actual problem. You certainly haven’t laid it out here. As mentioned above, you should also be working with your cardboard supplier so he understands your problem and can recommend the best material and construction methods. You may even have to pay attention to the orientation of the material grain, obviously so, if it is corrugated cardboard. What about loading, sheet size, buckling, etc.?
