Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...

STABLE TRIAXIALITY IN GERMANIUM AND SELENIUM ISOTOPES
, 2013 Total-Routhian-surface calculations by means of the pairing-deformation-frequency self-consistent cranked shell model have been carried out for germanium and selenium isotopes, in order to search for possible stable triaxial deformations of nuclear ...

Triaxiality dynamics of quadrupole excitation in even-even heavy nuclei
, 2023 In the framework free triaxiality model branching ratio reduced E2-transitions probabilities are studied for the full region changes of the triaxiality parameter. The variables of quadrupole deformations $\beta_2$ and $\gamma$ are dynamic.

Deep Underground Science and Engineering, EarlyView.This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Triaxiality of the ground states in the
, 2016 We have performed calculations for the ground states in 174W by using the projected total energy surface (PTES) calculations. Both the ground state (g.s.) band and its γ band reproduce the experimental data.

Yielding of Sand in Triaxial Compression
Soils and Foundations, 1974 ABSTRACT By employing different kinds of stress paths drained triaxial compression tests were conducted on sand samples having several densities. In the course of complicated cycles of stress change, the states of stress at which plastic deformations begin to take place were determined.

Jeans Solutions for Triaxial Galaxies [PDF]
, 2003 The Jeans equations relate the second-order velocity moments to the density and potential of a stellar system. For general three-dimensional stellar systems, there are three equations, but these are not very helpful, as they contain six independent moments.
