Energy-based ue - εvp coupled incremental model of saturated marine coral sand subjected to cyclic loading

Applied Ocean Research
Evaluating the stability of coral islands and reefs in dynamic marine environments, such as waves, tsunamis, storm surges, and earthquakes, is a critical scientific issue in the field of marine geotechnical engineering.

Seepage and deformation characteristics of sliding-zone soils under cyclic seepage pressure

Journal of Rock Mechanics and Geotechnical Engineering
Numerous incidents and failures of landslides in reservoir areas are attributed to water level fluctuations, which frequently induce cyclic changes in seepage pressure within the soil masses.

Experimental study on development patterns of volumetric strain and predictive modeling for saturated coral sands

Yantu gongcheng xuebao
The coral sand has better drainage conditions, and the drainage deformation of the saturated coral sand under earthquake and wave loads can easily cause damage to the seabed and nearby structures.

Deformation and failure characteristics of weathered granite under uniaxial compression

AIP Advances, 2019
In this paper, we have examined the crack formation of weathered granite by monitoring acoustic emissions (AE) under uniaxial compression. Except for the uniaxial compressive strength (UCS), the thresholds have been determined for crack closure, crack ...

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Analysis of freezing and thawing processes in clay with freeze-induced compression (FIC) model

Soils and Foundations
Fine-grained soils generally exhibit significant permanent compression due to freezing and thawing cycles. The nature of this compression was explored through the numerical analysis of two series of freezing (and thawing) experiments involving a wide ...
