Hockey Puck Squish in Real Time
Added 2014-04-05 03:28:55 +0000 UTCRemember the sped up footage of the hockey puck smash? Here it is in real time with the displacement vs force data.

Nice stuff. BTW, I am from Brazil (Rio de Janeiro).
2014-04-07 21:03:46 +0000 UTCIt's the measure of "vertical squish".

2014-04-05 14:08:55 +0000 UTCIs there any chance that the itunes freebee's can end up on Google Play as well? Since google have about 75% of the market share I'd think of it as expanding your audience... :)

Generally this is measured with an LVDT either integral to the machine or attached externally. Materials behave linearly when loaded in the "elastic" region. Once this is surpassed the material behaves non-linearly in the "plastic" region. I believe the puck actually "failed" early on in the test when the curve exhibited rapid up and down motion, this may be where the puck material was actually reaching its compressive yield strength. However, this was not an ideal setup to actually measure the material property and more just a neat experiment to see what happens and how much load and deformation the puck can actually take!
2014-04-05 04:14:23 +0000 UTCDefinitely watched the whole thing thru! I used to do mechanical testing and do NDT now, so I loved it! I'm from Pittsburgh, PA.
2014-04-05 04:08:17 +0000 UTCIs the "displacement" the distance by which the edge of the puck is shifted outwards when it's being squeezed? Why is the curve non-linear? Does that have anything to do with the shape of the puck or just the material? Did the puck actually "break"?
