HELIX UNCOILING MODES OF SHEARED CHOLESTERIC LIQUID CRYSTALS

摘要

This work presents an analysis that identifies the two prominent mechanisms that govern the helix uncoiling of sheared cholesteric liquid crystals. In the presence of free surface orientation helix uncoiling proceed by pitch expansion of traveling orientational waves, and in the presence of fixed surface orientation helix uncoiling proceeds via compression of elastic boundary layers.
