ALD Derived Li2O Layer Stabilizing Solid Electrolyte Interphase of Silicon/Carbon Anodes for Lithium Storage

Carbon Energy, EarlyView.
A durable solid electrolyte interphase (SEI) is essential for mitigating the mechanical fracture and interfacial instability of silicon anodes under strong electrochemical‐mechanical coupling. Herein, a uniform Li2O layer was accurately deposited on the Si/C composites to regulate the growth characteristics of SEI.

Neural Stress Fields for Reduced-order Elastoplasticity and Fracture [PDF]

, 2023
We propose a hybrid neural network and physics framework for reduced-order modeling of elastoplasticity and fracture. State-of-the-art scientific computing models like the Material Point Method (MPM) faithfully simulate large-deformation elastoplasticity

Modeling and experimental validation of bolt–grout bond–slip behavior for deep underground excavation support

Deep Underground Science and Engineering, EarlyView.
A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such

FE-BE Coupling Methods for Elastoplasticity [PDF]

Communications in Numerical Methods in Engineering, 1997
Summary: Nonlinear physical systems of infinite extent are conveniently modelled using FE-BE coupling methods. By the combination of both methods, suitable use of the advantages of each one may be obtained. Several possibilities of FEM-BEM coupling and their performance in some practical cases are discussed in this paper.
