Analysis of plastic zones in surrounding rocks around a circular tunnel considering the effect of intermediate principal stress and heterogeneity [PDF]

MATEC Web of Conferences, 2019
Based on a modified Mohr-Coulomb criterion with a non-uniform coefficient, a calculation method of plastic zone boundary of surrounding rocks in a circular tunnel in non-uniform stress field is established.

Tidal Coulomb Failure Stresses in the northern Andean intermediate depth seismic clusters: Implications for a possible correlation between tides and seismicity [PDF]

Tectonophysics, 2019
A recent statistical analysis of the relationship between tides and seismic activity in Colombia has suggested the existence of correlation anomalies for the case of intermediate depth events in the Bucaramanga nest and the Cauca cluster (Moncayo et al., 2019).

Structural and Dynamic Properties of Lipid‐Coated Gold Nanoparticles

Advanced Materials Interfaces, EarlyView.
Atomistic molecular dynamics simulations reveal how lipid chemistry governs the behavior of coatings on the surface of a gold nanoparticle. Variations in headgroup charge and acyl‐chain saturation produce distinct monolayer‐like lipid organization, ranging from compact, ordered coatings to extended, dynamic shells. These findings establish a foundation

Stress-dilatancy Relation for Mohr-Coulomb Soils Following a Non-Associated Flow Rule [PDF]

, 2010
Rowe\u27s stress–dilatancy relation for frictional (cohesionless) materials has been a cornerstone of soil mechanics. The original derivation of this relationship was based on incorrect energy minimisation considerations, but the relationship was proven ...

Numerical Simulation of the Influence of the Baihetan Reservoir Impoundment on Regional Seismicity

Applied Sciences
The Baihetan Reservoir is built for hydropower in China. The rise of the reservoir water leads to a series of earthquakes in the surrounding area. This study proposes fully coupled equations of pore-viscoelasticity and a parallel partition mesh model to ...

STABILITY ANALYSIS OF SLOPES USING A DOUBLE SLIDING MODEL

Journal of Engineering, 2003
Experience with Bishop's method, using the shear strength parameters c and obtained fron triaxial compression tests seems to indicate that the values of the safety factor obtained in this way are relatively large.
