Material properties non-linear 1

[Relevart]

Folks,
Can anybody help? I am trying to explore behavior different materials (metals) beyond elastic deformation at various temperatures.
I used to have Instron machine with a tech in the test lab few years back, but now I don't have a lab :-( and have to search for data, which turns out takes more time than set up prep, solution and had it run all together together. Were do you folks go for non linear properties of materials, other then Matweb, metals and plastic as well as rubber?
Thanks for any help

There is a materials forum...you may want to try it for such a diverse group of materials. For metals, there is Mil-Handbook-15 as well as ASM International produces a handbook. For plastics, depending on which kind of plastic (thermoset, thermoplastic, etc.) Mil-Handbook-17 may give you some information...I'm sure there are other references. For rubber...good luck! Hyper-elastic materials information is hard to come by from what I can tell.

Some polymer and elastomer material models for FEM analysis can be found at

It seems that most of it is made by ABAQUS users.

Mil-Handbook-5 (now MMPDS) for metals has stress-strain curves. Search the Aircraft Engineering forum for links on where to find a copy. Mil-Handbook-17 (composite materials) doesn't have any stress-strain curve data.

The ASM book you want is the Atlas of Stress Strain Curves.
