Dissipated energy in undrained cyclic triaxial tests [PDF]

, 2015
Energy-based methods are an emerging tool for the evaluation of liquefaction potential. These methods relate excess pore water pressure build-up to seismic energy dissipated per unit volume.

The formation of CDM haloes I: Collapse thresholds and the ellipsoidal collapse model

, 2014
In the excursion set approach to structure formation initially spherical regions of the linear density field collapse to form haloes of mass $M$ at redshift $z_{\rm id}$ if their linearly extrapolated density contrast, averaged on that scale, exceeds ...

Modeling of Crack Propagation in Ductile Materials Under Cyclic, Proportional and Non‐Proportional Loading Conditions

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The paper addresses the numerical calculation of multi‐axial fatigue crack propagation in ductile materials under proportional and non‐proportional cyclic loading conditions. The analysis is based on a phase field fracture theory proposed in earlier work, which describes crack propagation on the basis of the evolution of plastic strain.

Improvement of shear strength design of a road structure. Part 1. Deformations in the Mohr – Coulomb plasticity condition

Инженерно-строительный журнал, 2015
The article presents the Mohr – Coulomb plasticity condition modified by incorporating a third parameter depending on sample axial deformation value for which sliding planes are formed and developed under triaxial compression.

Experimental Simulation Investigation on Mechanism and Criterion of Impact‐Induced Rockburst in Gaoloushan Deep Tunnel

Energy Science &Engineering, Volume 13, Issue 8, Page 4252-4266, August 2025.
ABSTRACT During the excavation of a deep‐buried tunnel by the drilling and blasting method, the dynamic stress of blasting may cause the disorderly release of high energy in the rock mass during the blasting process of deep high‐energy rock. Blasting vibration is one of the main factors inducing dynamic disasters (such as rockbursts) in the surrounding

Closed‐Form Hypoplastic Solutions for Normally Consolidated Soil in Element Tests

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 11, Page 2492-2505, 10 August 2025.
ABSTRACT The hypoplastic theory has gained significant attraction in the geomechanics community for constitutive modeling and numerical simulation. However, the absence of an analytical benchmark for numerical simulations incorporating the hypoplastic model remains a notable gap. This study revisits the basic hypoplastic model for normally consolidated

A DEM Model for Assessing the Mechanical Effects of CO2 Alteration in a Carbonate Rock

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 11, Page 2559-2573, 10 August 2025.
ABSTRACT CO2 injection in the subsurface is considered an option to improve oil and gas production and, more recently, to store CO2. Consequently, there is a need to better understand the interactions between CO2 and rock deposits. Among the primary deposit candidates are carbonate rocks.

Rate and Pressure Dependence of Dilatancy and Fault Strength in Partially‐Drained Laboratory Fault Zones

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract The dynamics of fluid flow within faults plays a critical role in the evolution of fault strength through the seismic cycle. The key processes that control how fluids affect fault slip behavior are the evolution of fault porosity and fluid recharge and drainage during slip that, in turn, determine dilational strengthening or compaction ...
