the bends

Acute decompression sickness, the chokes Internal medicine A clinical complex caused by rapid whole body decompression, with intravascular 'boiling' of nitrogen, and resultant M&M in scuba divers and high-altitude pilots or workers in high-pressure environments–eg, caissons–in chronic decompression sickness Clinical Headache, N&V, vertigo, tinnitus, dyspnea, tachypnea, convulsions, shock, joint and abdominal pain; nitrogen gas in the brain causes 'boxcar' air bubbles in meningeal vessels separating the blood 'column', potentially causing death. Cf Caisson disease.

It was hypothesized that decreasing the rate of strain and increasing the MC would decrease the level of work required to produce the bend and decrease the probability of failure.
Among the variables known or believed to be important in successful bending are the force required to affect the bend, the bend radius, the displacement, and the time needed to produce the bend.
Closed loop adaptive forming works because the bend angle can be measured from the outside of the part, in real time, using a combination of a mechanical sensor and an "expert" database of information.
