Abstract
Periodic deformations spontaneously arising in hybrid aligned nematics are studied numerically. The so-called splay stripes are considered for material parameters close to those known for 5CB and for the saddle-splay elastic constant k24 values allowed by the Ericksen inequalities. The role of finite azimuthal anchoring on the planar boundary surface is investigated. The director distribution is determined for various azimuthal anchoring parameters. It is found that azimuthal anchoring suppresses the periodic deformations, damping their amplitude and decreasing all the parameter ranges for which the stripes exist. For the material constants considered, this effect is more pronounced for stripes which are realized for a negative k24 elastic constant, than for stripes arising if k24>0.
