This article studies equilibrium singular configurations of gels and addresses open questions concerning gel energetics. We model a gel as an incompressible, immiscible and saturated mixture of a solid polymer and a solvent that sustain chemical inte

We analyse a model of polyelectrolyte gels that was proposed by the authors in previous work. We first demonstrate that the model can be derived using Onsager's variational principle, a general procedure for obtaining equations in soft condensed matt

We derive a model of the coupled mechanical and electrochemical effects of polyelectrolyte gels. We assume that the gel, which is immersed in a fluid domain, is an immiscible and incompressible mixture of a solid polymeric component and the fluid. As

We formulate a nonlinear continuum theory of flow of chiral smectic C liquid crystals (C*) involving molecular director, layer order parameter, polarization vector, flow velocity, and hydrostatic pressure fields. In addition to chiral orientational o

We study a system of nonlinear second order ordinary differential equations modeling Poiseuille flow of liquid crystals with variable degree of orientation, at the limit of large Ericksen number. The system is singularly perturbed and degenerate, and

We consider an evolution system, describing the time-dependent behavior of nematic liquid crystals with variable degree of orientation within the continuum model of Ericksen. We establish a dissipation relation and prove both the global existence of

Molecules of a nematic liquid crystal respond to an applied magnetic field by reorienting themselves in the direction of the field. Since the dielectric anisotropy of a nematic is small, it takes relatively large fields to elicit a significant liquid

We examine the multiplicity of steady state solutions of polymeric liquid crystals in shear flow regimes. We study flow configurations exhibiting two or more phases arranged as bands parallel to the flow. We discuss stability of such texture configur

We examine the stability of flows of liquid crystal polymer materials under shearing perturbations. We apply the Laplace transform method to study the well-posedness of the resulting initial-boundary value problem and interpret the singularities of t
