Energy Cost of Dynamical Stabilization: Stored versus Dissipated Energy [PDF]

open access: yesEntropy, 2022
Dynamical stabilization processes (homeostasis) are ubiquitous in nature, but the needed energetic resources for their existence have not been studied systematically. Here, we undertake such a study using the famous model of Kapitza’s pendulum, which has

Energy-based indicators and optimization of coal pillar width in gob-side entry driving [PDF]

open access: yesScientific Reports
Gob-side entry driving is widely applied in deep coal mines, where rapid unloading of surrounding rock on the gob side induces stress redistribution, and the coal pillar is consequently regarded as a key load-bearing structure.

A dissipated energy comparison to evaluate fatigue resistance using 2-point bending

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2014
Fatigue is the main failure mode in pavement engineering. Typically, micro-cracks originate at the bottom of asphalt concrete layer due to horizontal tensile strains.

Dissipated Energy and Pore Pressure Generation Patterns in Sands and Non-Plastic Silts Subjected to Cyclic Loadings

open access: yesGeotechnics
The factors that influence dissipated energy and pore pressure generation patterns with respect to the cycle ratio and dissipated energy ratio were analyzed using the results of cyclic triaxial and cyclic direct simple shear tests.

Analysis of energy dissipation in resistive superconducting fault-current limiters for optimal power system performance [PDF]

open access: yes, 2011
Fault levels in electrical distribution systems are rising due to the increasing presence of distributed generation, and this rising trend is expected to continue in the future.

A model for rock dissipated energy estimation based on acoustic emission measurements

open access: yesFrontiers in Earth Science, 2023
The temporal domain of dissipated energy during rock damage and failure is commonly quantified using loading and unloading tests or elastic mechanics-based theoretical calculation methods. However, these approaches cannot be applied to obtain the spatial

Energy dissipation mechanism and damage model of marble failure under two stress paths [PDF]

open access: yesFracture and Structural Integrity, 2014
Marble conventional triaxial loading and unloading failure testing research is carried out to analyze the elastic strain energy and dissipated strain energy evolutionary characteristics of the marble deformation process. The study results show that the

Experimental study on dynamic and dissipated energy behaviors of saturated red mudstone fill materials

open access: yesYantu gongcheng xuebao, 2023
The deformation control of subgrade plays a key role in ensuring the smoothness of the railway. The deformation of subgrade is dependent on the traffic loads and the dynamic behavior of subgrade fill materials.
