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.

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.
An ancillary objective of these experiments was to show that a measure of success in bending could be developed by calculating the amount of work required to produce the bend and comparing the results to the work to maximum load data for the species.
In conventional bending, variation in material characteristics causes deviation of the bend angle.
