Dynamics of a colloidal glass during stress-mediated structural arrest

open access: yes, 2010
We employ parallel superposition rheology to study the dynamics of an aging colloidal glass in the presence of a mean field stress. Over a range of intermediate stresses, the loss modulus exceeds the storage modulus at short times but develops a maximum ...

Fault reactivation by fluid injection: Controls from stress state and injection rate [PDF]

open access: yes, 2018
We studied the influence of stress state and fluid injection rate on the reactivation of faults. We conducted experiments on a saw-cut Westerly granite sample under triaxial stress conditions.

Relations and Links Between Soil Mechanics, Porous Media Physics, Physiochemical Theory, and Effective Medium Theory

open access: yesFrontiers in Physics, 2019
Modern soil mechanics (geotechnical engineering) was developed as a branch of civil engineering from the 1920's. While modern porous media physics was developed as a branch of physics and applied mathematics from roughly the same period of time.

Dynamic Response of Bottom-Sitting Steel Shell Structures Subjected to Underwater Shock Waves

open access: yesInfrastructures
This study examines the dynamic response of bottom-sitting steel shell structures subjected to underwater shock waves. A computational framework integrating the Arbitrary Lagrangian Eulerian (ALE) method was implemented in finite-element analysis to ...
