[Closed] help! Vickers to MPa or GPa!

....if you are asking is there a way to equate Vickers Hardness to elastic modulus in SI units, then there might be answer to that! 😉

EDIT: ...and there you go!

Yes, bristolbiker, that's what I'm looking for 🙂 I've only found the gordenengland link (and copies of)... so far

<looks confused> Is that not enough? Seems to give you exactly what you've asked for, or have we missed something? </looks confused>

that's OK? Great. I was looking for another method/ description to validate the GE one.

Think this is the best you'll do, and should be a pretty good correlation for metals, although directly relating 'hardness' to 'stiffness' seems a bit iffy being stictly two different physical properties. I know it starts to go a bit wrong if you're using a material like rubber....

yeah, that's right. Although this for superhard coatings, i'm not sure how well it will work either

Even if it's v hard, you'll be alright-ish (IIRC) provided you don't distort the result by fracturing the surface local to the indentor and so giving an aritifically low indentation force.

Go on then, what's it for... curiosity well and truly piqued 😉
