Add article description

A hemihelix is a curved geometric shape consisting of a series of helices with alternating chirality, connected by a perversion at the reversals.[1][2]

The formation of hemihelices with periodic distributions of perversions in slender structures is understood in terms of competing buckling instabilities generated by in-plane stresses.[3]
