Average antiplane motion in an elastic solid containing a layer of randomly distributed cracks
The propagation of antiplane waves in an elastic solid containing a random distribution of cracks that are parallel to each other, and oriented at an arbitrary angle relative to the direction of the incident wave, is ...
Numerical simulation of reactive flow and transport through the subsurface
Convection-dominated fluid transport problems have long resisted accurate and cost-effective numerical solutions. The near hyperbolic nature of the problem causes spurious oscillations in most numerical schemes or avoiding ...
A study of viscous effects in seismic modeling, imaging, and inversion: Methodology, computational aspects, and sensitivity
Real Earth media are anelastic, which affects both the kinematics and dynamics of propagating waves: Waves are attenuated and dispersed. If anelastic effects are neglected, inversion and migration can yield erroneous ...
Experimental/analytical approaches to modeling, calibrating and optimizing shaking table dynamics for structural dynamic applications
This thesis presents an Experimental/Analytical approach to modeling and calibrating shaking tables for structural dynamic applications. This approach was successfully applied to the shaking table recently built in the ...
Nonstationary ground motion model and applications to analysis and design of earthquake-resistant structures
To account for the uncertainties that are inherent in the definition of earthquake ground motions, this investigation is carried out in a probabilistic framework. A new, versatile, stochastic earthquake ground motion model ...
