"hardening factor"
"hardening factor"
(OP)
SW2009.0.
Trying to add a custom material.
Under the Properties tab, they ask for a
"Hardening factor", parenthetically state it should be between 0 and 1, and give units of lb/in^2, which makes no sense.
For 316 stainless, they've got a value of 0.000123282 in there, suggesting that maybe it can be calculated from something.
I'm trying to add Incoloy 25-6MO, which is chemically similar to 316 except for having twice the Nickel and some Molybdenum, which makes it harder and stronger and makes it work harden faster than 316.
I've been out of school a long time; what are they talking about here?

RE: "hardening factor"
I can't for the life of me figure out what this might be used for (inside of Solidworks, that is). What's your end goal? Is this "Hardening Factor" even needed?
RE: "hardening factor"
There's a curve in the 25-6MO data sheet relating Vickers hardness number to percent cold work, but it's not a straight line, so I don't know how you would extract a 'factor' out of it... or what you would do with such a factor.
I thought maybe it had to do with SW's sheet metal functions. I've used 6MO to make welded tubing and such, so I know it 'fights back' much more than 316 does.. but like you, I can't conjecture what SW would do with that information.
Thanks for trying.

I have some reading to do. Thanks to all.

RE: "hardening factor"
That's along the lines of what I was thinking. Are you entering this information in Solidworks to feed it into BlankWorks or something similar? I'm not familiar with this program so I don't know if it uses the Solidworks material properties or not.
In any case, if this hardening factor is used in blank development it seems that this number may be based on empirical data much like K-factor, etc.
RE: "hardening factor"
There may be room for improvement. Local sources say that SW's blank calculations were inaccurate with default parameters as delivered. They did some test bends and developed their own tabular offsets, instead of using the test bend data to induce SW to produce accurate blanks on its own. I asked; they didn't preserve the raw data.
... Which means that the timesaving tool doesn't save quite as much time as it could, because nobody ever has time to do the one-time fine tuning. That's not a local problem.

He mentions it here. To do with strain hardening.
A Google for "Hardening factor tensile testing" gives a few esoteric paper references.

RE: "hardening factor"
No idea - surely a "factor", by definition is unitless?
Suggest a post in the stainless steel forum as they seem to know all about it. Saves guessing here.
