A lot of times however you find vehicles like tanks still have weak spots. while the armor might hold together other internal parts such as inner support structure, welds, bolts, might begin to weaken. All if this assuming the armor doesnt absorb sound
Right, and how long would it take for it to even cause slight damage? And what are you taking about armor absorbing sound? I've already said that if said material is tempered, the brittleness is gone and it wouldn't work.
Yes, and you would get even better results with a anti-matter cutter! Wait, that's still far dumber than space-rifting cutter!
Seriously, vibro blade are mostly used in setting where energy blade aren't available. Maybe the tech aren't advance enough, being expensive, power hunger, blah blah blah.
I was referring to current plasma cutters, and besides, when you are trained in metallurgy and tool making, there are a lot of alarm bells that tend to come up.
Anyways, vibro blades would need to be made of material that wouldn't dull so quickly especially since the contact on whatever material you are cutting would accelerate the wear on it. That means the material would have to perform much like adamantium for it to stay effective to do any damage. That also doesn't take into account the massive mechanical stress in creating and sustaining the vibration.
