[PSUBS-MAILIST] Impact Calculations..

["James Warner" <james@whototake.com>]

Has anyone that is currently designing or has designed their sub, calculated
the speed at which they could impact an object while at depth, and not have
to worry about a rupture?  I would think that a sharp impact in a
concentrated area on an acrylic dome or your pressure hull that already has
even pressure distrubuted about it, would cause a rupture fairly easily?  Or
is this just factored into the safety factor of your sub?  Thanks.
