Development of centrifuge model test equipment for canals in seasonal frozen areas under cyclic action of wetting-drying and freeze-thaw

Yantu gongcheng xuebao, 2020
Seasonal frozen soil accounts for more than half of China's land area. The canals located in the seasonal frozen areas undergo a wetting-drying and freeze-thaw cycle with seasonal change and periodic change of water supply and suspension, thus causing ...

A Holistic Stabilization of the Anode in Lithium‐Sulfur Batteries Through a Ternary Alloy Fusion

Advanced Functional Materials, EarlyView.
LiTeAl anodes fabricated through a scalable thermal fusion technique holistically addresses the stability issues faced by lithium‐metal anodes in lithium–sulfur batteries. Aluminum forming a skeletal network with lithium suppresses dendrite growth and enhances energy density, while tellurium forming a robust SEI facilitates Li+‐ion flow.

Applicability of additive mass method in density tests on soil-mixture materials

Yantu gongcheng xuebao, 2023
The additive mass method (AMM) has been applied in the density tests on different materials of many earth-rockfill dams. With the development of hydropower projects in recent years, the soil-rock mixtures (S-RM) with wide gradation and high fines content

Application of displacement multi-point constraint refinement method in simulation of concrete-faced rockfill dams

Yantu gongcheng xuebao, 2020
In the numerical simulation of a concrete-faced rockfill dam, to consider the accuracy and efficiency of calculation, the concrete slab can be simulated using fine mesh and the rockfill can be simulated using relatively coarse mesh. Therefore, the proper

Plastic strain directions of rockfill materials during loading and creeping

Yantu gongcheng xuebao, 2018
The determination of the incremental plastic strain direction (IPSD) is one of the kernels in elastoplastic constitutive models. It is generally assume that the IPSD depends only on the stress states and is not influenced by the stress increments.

Numerical analysis of optimization of revetment structures of soil bank slopes of inland rivers

Yantu gongcheng xuebao, 2020
The revetment structure can reduce the damage of soil bank slopes caused by water erosion, but its influences on the physical and mechanical processes such as seepage and deformation of the existing bank slopes should be fully considered in practice ...
