Analysis of Energy Transmission and Deformation Characteristics of Coal-Rock Combined Bodies

open access: yesGeofluids, 2022
A coal-rock system is a common combination form in coal mines. In order to explore the energy interchange law of a coal-rock combined body and the interaction relationship between the two bodies, loading tests of coal-rock combined bodies with different ...

Effect of Nonparallel End Face on Energy Dissipation Analyses of Rocklike Materials Based on SHPB Tests

open access: yesShock and Vibration, 2019
To evaluate the effect of nonparallel end face of rocklike specimens in SHPB tests, the characteristics of energy dissipation are analyzed based on numerical simulations for end-face nonparallelism from 0% to 0.40% and Young’s modulus from 14 GPa to 42 ...

Numerical modeling on strain energy evolution in rock system interaction with energy-absorbing prop and rock bolt

open access: yesInternational Journal of Mining Science and Technology, 2023
The interaction mechanism between coal and rock masses with supporting materials is significant in roadway control, especially in deep underground mining situations where dynamic hazards frequently happened due to high geo-stress and strong disturbed ...

On the strain-energy density in linear elasticity [PDF]

open access: yesJournal of Engineering Mathematics, 1973
SUMMARY Standard results from matrix theory are used to derive optimal upper and lower bounds for the strain-energy density in terms of the norm of the stress tensor in two and three dimensions. The approach also yields directly necessary and sufficient conditions for positive-definiteness.

Strain-controlled fundamental gap and structure of bulk black phosphorus

open access: yes, 2016
We study theoretically the structural and electronic response of layered bulk black phosphorus to in-layer strain. Ab initio density functional theory (DFT) calculations reveal that the strain energy and interlayer spacing display a strong anisotropy ...

Ductile crack propagation with the strain energy density criterion [PDF]

open access: yesEngineering Fracture Mechanics, 1985
The strain energy density criterion is used to characterize subcritical crack growth in a thin aluminum alloy sheet undergoing general yielding. A finite element analysis which incorporates both material and geometrical nonlinear behaviors of the cracked sheets is developed to predict fracture loads at varying crack growth increments.

Analytical and finite-element study of optimal strain distribution in various beam shapes for energy harvesting applications [PDF]

open access: yes, 2016
Due to the increasing demand for harvesting energy from environmental vibration, for use in self-powered electronic applications, cantilever-based vibration energy harvesting has attracted great interest from various parties and become one of the most ...

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

open access: yesFEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Paleotectonic residual strain energy in Southwest China

open access: yesGeodesy and Geodynamics, 2015
Based on the orthotropic elastic theory of rock masses, the X-ray method was used to measure the distribution of macro-residual strain energy density along a depth profile, using core samples taken from 47 large-aperture deep boreholes in four regions of
