The Research Center for Mechanics of Solids, Structures and Materials at the University of Texas at Austin invites applications for an open position as Post-doctoral Fellow. The specific project involves collaboration with the University of Texas MD Anderson Cancer Center in Houston and requires the Fellow to work at both institutions. The work involves experimental characterization of tissues and surgical remodeling, and development of computational modeling of surgical reconstruction.

The Poisson's ratio characterizes the resultant strain in the lateral direction for a material under longitudinal deformation.  Though negative Poisson's ratios (NPR) are theoretically possible within continuum elasticity, they are most frequently observed in engineered materials and structures, as they are not intrinsic to many materials.  In this work, we report NPR in single-layer graphene ribbons, which results from the compressive edge stress induced warping of the edges.

In the present work, we study morphologies arising due to competing substrate interaction, electric field, and confinement effects on a symmetric diblock copolymer. We employ a coarse-grained nonlocal Cahn-Hilliard phenomenological model taking into account the appropriate contributions of substrate interaction and electrostatic field. The proposed model couples the Ohta-Kawasaki functional with Maxwell equation of electrostatics, thus alleviating the need for any approximate solution used in previous studies.
