Bio-inspired Network Dynamics and Geomechanics

Goals

To predict soil and rock THCM behavior during heat and fluid injection and extraction, design new geomaterials to optimize the fuel cycle, and recommend strategies for resource and waste management. To build demonstration experimental set ups, to develop graphical media and to archive simulations ready for use in soil mechanics undergraduate course and geomechanics graduate courses.

Issues Involved or Addressed

What are the scales and processes governing soil and rock behavior? How much energy does it take to produce energy? Is hydraulic fracturing sustainable? How to ensure long-term reliability of geological storage facilities? What are our energy resources for 2050? Specific research areas include:

Multi-scale crack propagation in crystalline and porous media, or multicrack
Multi-scale modeling of stiffness in sane, damaged and repaired dentin for curing tooth cavities
Modeling of anisotropic damage in concrete repaired by epoxy injection
Simulation of tensile, shear and mixed crack propagation and coalescence in rock
Comparison of cohesive zone models and extended finite element methods for crack coalescence
Multi-scale crack networks in crystalline and porous media, or network
