Fracture behavior in battery materials

Fracture Problems in Composite Materials

In this paper a series of fracture problems in composite materials are identified, their methods of solution are briefly discussed, and some sample results are presented. The main problem of interest is the determination of the stress state in the neighborhood of localized imperfections such as cracks and inclusions which may exist in the composite. Particular emphasis is placed on the evaluati...

Fracture of Dental Materials

Battery Materials for All - Solid State Batteries

The Grey group tackles a broad range of materials science and energy storage challenges that include various aspects of solid state chemistry, spectroscopy, and theoretical studies. To understand and control the materials that are desirable for energy storage applications, we use a suite of synthetic and analytical techniques, including diffraction, microscopy, solid state NMR, and computation....

Behavior of a hydraulic fracture in permeable formations

The permeability and coupled behavior of pore pressure and deformations play an important role in hydraulic fracturing (HF) modeling. In this work, a poroelastic displacement discontinuity method is used to study the permeability effect on the HF development in various formation permeabilities. The numerical method is verified by the existing analytical and experimental data. Then the propagati...
