Abstract

The second order bulk elastic constants, characterizing the squares of second order derivatives of the director, deeply influence the behavior of weakly anchored nematics. Here the critical thickness of a Hybrid Aligned Nematic cell, strongly anchored on the planar side, is calculated as a function of the anchoring strength at the homeotropic side, of the mixed splay-bend, and of the second order bulk elasticity.
