This movie shows the crack propagation in the harmonic (linear) material. The speed in this case is transsonic after the emergence of the daughter crack.

    well technically speaking, they are caused by objects impacting each other. an object moving at subsonic speed is impacting the air constantly, and as it reaches hypersonic speed, the boom occurs due to the object moving faster than the waves which it creates

    χαχα, είναι φοβερός πράγματι!

  • Any possiblity of having you rework this as animation of same, in osillation? Perhaps a beat calculation of 360 beats per second?

  • @NCC1701J That has nothing to do with it. You will never hear a sound the instant it is made. You're thinking of the sound the stone makes as it passes you, not on impact. On impact the objects involved vibrate, this combined with the displaced air creates a sound wave. Sonic booms aren't caused by objects impacting each other.

  • Yeah... ok...

  • I love wewannawatch description of this video ( and i still don't get it lol )......."DAUGHTER CRACK" lol.............awesome! hahahahahahaaa!

    thanks for trying to explain this @@@ obsidianpirate.........but im afraid this video is visually beautiful and confusing. If this is a scientific concept.........i'm really interested in understanding this video and its language. Thanks...........HAHAHAHAAAAAA "DAUGHTER CRACK !" classic! if someone got the time, please explain it to me!

  • weird

  • is this in the the position or frequency domain?

  • ummm... lets explain it like this... see the wave that's left from the original cone?... that is the broken sound barrier... moves slower than the tip of the cone, and the cone itself...
