Obtaining material stress-strain curve
Obtaining material stress-strain curve
(OP)
Hello all,
I would like to get some input from experienced engineers and materials scientists. I am after the stress-strain curve to use the data for my FE analysis material model. The material is a particular ASTM material. I have not been able to find the material data available and so it looks like I will need obtain the data myself through an experiment, but have no experience obtaining this kind of data.
I would really appreciate some input as the equipment and tests pieces required to obtain such data. Indeed if there are any shortcuts or tricks of the trade I would really like to hear them.
Thanks-you.

maybe we can help.
if you need to develop it for yourself, you need a tension loading machine, standard tension specimens, and a notebook

I have contacted them but apparently the standard does not contain a stress-strain curve (there only so much you can fit into 4 pages). If some has access to the standard perhaps they wouldn't mind kindly confirming if the standard does have a stress-strain curve or not.
Because it is quite a specialist material in a specific form, most materials companies and materials testing companies (at least the ones I have contact with) can not help with this.
I look forward to any further input from the community, thanks.

If you have an actual sample of the material, then you should just have a certified lab test it for you. Machining a specimen and having it tensile tested costs ~ $100 in the USA. I imagine that it would be similar cost in the UK.

jpankask, thanks for confirming that the previous versions do not have a stress strain curve.
dhergr, thanks for your input, your right it is not a run of the mill steel. The company who use the material for there products say they do not have any stress-strain curve of the material. Being that it is proprietary like you say, gives me less of a chance of receiving it from them even if they did have it. There's no secrecy here, as I mentioned I need the stress-strain data for my material model in FEA to run stress and contact analysis, I am not sure what more I can say? What else would you like the know?
Thanks again so far everyone, any further inputs would be much appreciated.
