Large-eddy simulation (LES) and Reynolds-averaged Navier-Stokes (RANS) simulation of wind and wave forced oceanic turbulence in unstratified shallow water are performed in order to investigate the influence of wall modeling on results. The LES is also used to investigate the dependence of results on downwind and crosswind lengths of the computational domain, representative of a shallow shelf coastal ocean (10-to-30 m deep) unaffected by lateral boundaries.

We are concerned with underlying connections between fluids,
elasticity, isometric embedding of Riemannian manifolds, and the existence of
wrinkled solutions of the associated nonlinear partial differential equations. In
this paper, we develop such connections for the case of two spatial dimensions,
and demonstrate that the continuum mechanical equations can be mapped into
a corresponding geometric framework and the inherent direct application of
the theory of isometric embeddings and the Gauss-Codazzi equations through
examples for the Euler equations for fluids and the Euler-Lagrange equations
for elastic solids. These results show that the geometric theory provides an
avenue for addressing the admissibility criteria for nonlinear conservation laws
in continuum mechanics.

This work introduces a new microscopically-motivated model for the electromechanical response of elastomers:

The merit of this novel model is demonstrated in the following paper

The Integrated Soft Materials Lab (SML) is accepting applications for postdoctoral appointments in the areas of soft-matter electronics and multifunctional materials. The postdoctoral researchers will lead efforts to develop composites and integrated soft material architectures for sensing and actuation in wearable, deformable, and shape-programmable systems.  Applications will focus on artificial skin and muscle for autonomous soft robots, prostheses, and wearable computing.
