A theoretical foundation is developed for the active seismic reconstruction of fractures
endowed with spatially varying interfacial conditions (eg partially closed fractures, hydraulic …

Though well known for layer boundaries, the use of amplitude-versus-offset (AVO) variations
for non-welded boundaries like fractures is not yet investigated. Depending on the seismic …

When seismic waves travel through a fluid-saturated porous medium containing a fracture,
fluid pressure gradients are induced between the compliant fracture and the stiffer …

In this work, we consider a mathematical foundation for elastic-wave reconstruction of
multiply-connected fractures in a finite solid body by way of the Generalized Linear …

An analytic-numerical method to simulate the interaction of ultrasonic guided waves with
nonuniform interfacial imperfections in elastic multi-layered structures is presented. The …

The concept of topological sensitivity (TS) is extended to enable simultaneous 3D
reconstruction of fractures with unknown boundary condition and characterization of their …

The elastic compliance of a fracture can be spatially varying, reflecting the variation of
microscale properties of the fracture, eg, aperture, contact asperities, and fracture infill …

A non-iterative waveform sensing approach is proposed toward (i) geometric reconstruction
of penetrable fractures, and (ii) quantitative identification of their heterogeneous contact …

The spatial heterogeneity along a fracture is a key determinant for fracture‐associated
mechanical and hydraulic properties of the subsurface. Laboratory experiments have been …

We present new methodologies for the numerical solution of problems of elastic scattering
by open arcs in two dimensions. The algorithms utilize weighted versions of the classical …
