homogenization

In differential geometry, rigidity theory investigates whether a surface can deform by pure bending without stretching. The central problem is to find or disprove the existence of isometric deformations.

Classical examples in the "discrete" category include:

• The finite rigidity of convex polyhedra by Cauchy
• The infinitesimal rigidity of convex polyhedra by Dehn
• The existence of flexible (non-convex) polyhedra by Connelly

In the "smooth" category, we have:

Abstract

Successful applicants will work on the mechanics and thermodynamics of porous solids undergoing reactive flow within the scope of the DOE-funded center on Geo-processes in Mineral Carbon Storage (GMCS, https://gmcs.umn.edu). The mission of GMCS is to develop the fundamental science and engineering capability that will lead to realizing the full potential for large-scale subsurface storage of CO2 via mineralization.

Dear colleagues, 

We invite you to read our recent article, which proposes a multiband homogenization scheme and has been accepted to appear in JMPS (https://www.sciencedirect.com/science/article/pii/S002250962200182X)

Multiband homogenization of metamaterials in real-space: Higher-order nonlocal models and scattering at external surfaces

I have a few positions (funded by AFRL, ARO, etc) for MS or PhD (preferred) students at the University of Tennessee Space Institute (UTSI) and University of Tennessee Knoxville (UTK). The positions should start in January 2022 or at the latest Fall 2022. One of the positions requires US citizenship. The projects are in the following general areas:

I would like to share another article from my group just published in CMAME. I think this is an interesting approach towards the automatic generation of constitutive laws for arbitrary microstructures:

The article focuses on how to systematically create constitutive laws using only:

1) Available microstructural models

2) Machine learning techniques

The positions: I am looking to support two PhD students to work with me towards a mechanical understanding of morphing structures such as origami tessellations and lattice materials and metamaterials. By "understanding" I mean anything relevant to the theoretical and numerical modeling of these structures, in static and dynamic regimes, within the context of elasticity whether linearized or not as well as the fabrication and testing of toy models necessary to assess that "understanding".
