Biaxial liquid-crystal elastomers: a lattice model.
We present a simple coarse-grained lattice model for monodomain biaxial liquid-crystal elastomers and perform large-scale Monte Carlo simulations in the proposed model system. Orientational ordering--uniaxial or biaxial--reflects in sample deformations on cooling the system. The simulation output is used to predict calorimetry data and deuterium magnetic resonance spectra.
متن کاملSelf-Consistent Model of Roton Cluster Excitations in Liquid Helium II
Abstract We have proposed a model of roton cluster excitations in liquid helium II based on a Schrödingertype equation with a self-consistent confining potential. We have derived an equation for the number of atoms in roton excitations, which can be treated as quantum 3D solitons, depending on vibrational quantum numbers. It is shown that the smallest roton cluster is in the symmetric vibration...
متن کاملLiquid Crystal Lattice Models Ii. Confined Systems
Monte Carlo simulations of lattice spin models represent a powerful method for the investigation of confined nematic liquid crystals and allow a study of the molecular organization and thermodynamics of these systems. Here some models of confined liquid crystals, such as polymer dispersed liquid crystals, twisted nematic, in-plane switching liquid crystal displays and hybrid aligned films are d...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
A dynamic lattice model for heterogeneous materials
In this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. The Timoshenko beam theory is applied instead of the classical Euler-Bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. T...
