Submitted by Zeliang Liu on

A postdoctoral researcher position is open in the Integrated Design Automation Laboratoryat Northwestern University under the guidance of Prof. Wei Chen.  The postdoctoral researcher will work on systematic computational design methods that provide a seamless integration of design optimization, predictive materials modeling, processing/manufacturing, and data/informatics to enable the accelerated design and development of multiscale materials systems.

Prescribing Surface Strains to change Gauss curvature

Prescribing  Surface Strains to change Gauss curvature

To change Gauss curvature K of a surface we need to strain each differential shell element by virtue of Egregium theorem ( K is invariant if strain is zero in isometry mappings).

Can someone help with a geometrical problem where imposed strains are to be defined (at differential shell element level of a right circular cylinder) to obtain a surface of revolution with Gauss curvature +1 or -1 (sphere or pseudosphere) ? Or their isometric equivalents? Cylindrical coordinates may be used.

Modulating elastic band gap structure in layered soft composites using sacrificial interfaces

Submitted by Ahmed Elbanna on

A wide range of engineered and natural composites exhibit a layered architecture whereby individual building blocks are assembled layer by layer using cohesive interfaces. We present a novel mechanism for evolving acoustic band gap structure in a model system of these composites through patterning the microstructure in a way that triggers non-planar interfacial deformations between the layers as they are stretched.
