1. A method for demolding a composite part from a mandrel, the method comprising:
mechanically coupling a first arm of an extraction tool to a first arcuate portion of a composite part that has been hardened onto a mandrel;
mechanically coupling a second arm of an extraction tool to a second arcuate portion of the composite part; and
separating the composite part from the mandrel by iteratively performing the following operations until the composite part no longer contacts the mandrel;
elastically straining the first arcuate portion of the composite part via the first arm;
elastically straining the second arcuate portion of the composite part via the second arm; and
iteratively alternately increasing an elastic strain applied to the first arcuate portion and an elastic strain applied to the second arcuate portion.
