Possibly Detonation Velocity revisions

[Qawsedf234]

Currently we use detonation velocity in a lot of stuff, but this is what detonation velocity is: "Explosive velocity, also known as detonation velocity or velocity of detonation (VoD), is the velocity at which the shock wave front travels through a detonated explosive."

Now if you read the above you'll notice something extremely important: "the shock wave front travels through a detonated explosive."

In other words detonation velocity is the speed that the wave moves in the explosive and not the speed to moves at initially.

Using this official UN calculator I'm going to use two examples: TNT, which has a detonation velocity of 6,900 m/s, and C4 which has one at 8,092 m/s

• From a mere 0.3 meters (one foot) away the shockwave from TNT is reduced to 3,049 m/s or by over half of its original speed value
• From the same distance C4 is reduced to 3,266.8 m/s or a total speed reduction of 84.9577%

So any speed calc using detonation velocity is only valid if the feat happened under about 10 centimeters away from the explosive. Any further and the shockwave would massively be reduced in speed.

Wew

I don't really deal in explosive science I just think this makes sense

Huh. That seems extremely important and could affect quite a lot of calcs.

Oh my, that'll affect a lot of stuff but this seems correct to me as well. Though I'm certainty not an expert on this stuff.

 

[TheRustyOne]

Bump?

Was there a reason this was dropped, this seems like it's pretty important.

This was brought up long ago by Xcano, I had the impression that people took into account and limited these calcs (but I retired from calcs long ago too, so I had no idea it was implemented).

 

[TheRustyOne]

A quick check shows this is written in our explosion speed calculation page.

So maybe this isn't a big of an issue as I had originally thought.

If its included in there, then yeah. This isn't super important.
