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.

Dear Colleagues,

The 53rd Annual Technical Meeting of the Society of Engineering Science (SES2016) will be hosted by the University of Maryland (UMD) during 2-5 October 2016 (note the new conference date) at the College Park Marriott Hotel & Conference Center.  

There is a Ph.D. opportunity in my lab http://www.me.uh.edu/faculty/baxevanis supported by the Mechanical Engineering Department at the University of Houston on the microstructure-sensitive description of the deformation and failure response of shape memory alloys. Applications are sought from self-motivated students with a strong background on solid mechanics and FEA simulations. Should you be interested in the position, please, email your CV to tbaxevan at central dot uh dot edu.
