A two-dimensional limit equilibrium computer code for analysis of complex toppling slope failures

Journal of Rock Mechanics and Geotechnical Engineering, 2021
Evaluation of blocky or layered rock slopes against toppling failures has remained of great concern for engineers in various rock mechanics projects.

A note on linearized stability of Schwarzschild thin-shell wormholes with variable equations of state [PDF]

, 2015
We discuss how the assumption of variable equation of state (EoS) allows the elimination of the instability at equilibrium throat radius $a_0=3M$ featured by previous Schwarzschild thin-shell wormhole models.

Self-gravitating Newtonian models of fermions with anisotropy and cutoff energy in their distribution function

, 2014
Systems of self-gravitating fermions constitute a topic of great interest in astrophysics, due to the wide field of applications. In this paper, we consider the gravitational equilibrium of spherically symmetric Newtonian models of collisionless ...

How glasses explore configuration space

, 2002
We review a statistical picture of the glassy state derived from the analysis of the off-equilibrium fluctuation-dissipation relations. We define an ultra-long time limit where ``one time quantities'' are close to equilibrium while response and ...

Boundary distribution of top-coal limit-equilibrium zone in fully mechanized caving in steeply dipping coal seams

Geomatics, Natural Hazards & Risk, 2021
In fully mechanized caving mining, the earlier the top coal enters the limit-equilibrium zone, the easier it is for leakage to be induced in front of the support. As the dip angle of the seam increases, the leakage of the top coal in front of the support

On Equilibrium Dynamics of Spin-Glass Systems

, 2006
We present a critical analysis of the Sompolinsky theory of equilibrium dynamics. By using the spherical $2+p$ spin glass model we test the asymptotic static limit of the Sompolinsky solution showing that it fails to yield a thermodynamically stable ...

Three-dimensional limit equilibrium analysis of open pits [PDF]

Proceedings of the 2013 International Symposium on Slope Stability in Open Pit Mining and Civil Engineering, 2013
The analysis of slope stability in the design and ongoing operations of any particular open pit remains a difficult challenge. Slope failures and loss of equipment, mining time, and lives make stability concerns an issue which warrants research efforts.
