Risk analysis of distribution network outages under a typhoon–rainstorm–flood disaster chain

Energy Conversion and Economics, Volume 6, Issue 2, Page 126-139, April 2025.
Abstract The typhoon–rainstorm–flood disaster chain poses a significant flooding risk to urban distribution network (DN) equipment, often leading to power system outages. The increasing frequency and severity of this disaster chain in East Asia, driven by global warming, population growth, and land‐use changes, highlight the need for improved disaster ...

An Efficient Finite Difference Scheme for the 2D Sine-Gordon Equation

, 2017
We present an efficient second-order finite difference scheme for solving the 2D sine-Gordon equation, which can inherit the discrete energy conservation for the undamped model theoretically.

An Extended B‐Spline‐Based Material Point Method for Contact Problems

International Journal for Numerical Methods in Engineering, Volume 126, Issue 3, 15 February 2025.
ABSTRACT A novel Material Point Method (MPM) is introduced for addressing contact problems. In contrast to the standard multi‐velocity field approach, this method employs a penalty method to evaluate contact forces at the discretised boundaries of their respective physical domains.

Mapping 3D Overthrust Structures by a Hybrid Modeling Method

Earth and Space Science, Volume 12, Issue 1, January 2025.
Abstract A rational three‐dimensional (3D) geological model with complex characteristics generated on a small amount of data is a crucial data infrastructure for scientific research and many applications. However, reconstructing structures with multi‐Z values on a single point caused by folding or overthrusting is still one of the bottlenecks in 3D ...

Learning Correlations Between Computational Scale and Performance for Accurate Numerical Modeling: Application Case of Dam‐Break Flood Processes

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Scientists aim to accurately simulate and characterize complex natural phenomena, thus revealing the underlying natural laws or physical mechanisms governing these phenomena. Conventional physical experiments require significant time and cost, and numerical methods offer an alternative solution. However, modeling complex phenomena such as fluid flow in

Constitutive description of snow at finite strains by the modified cam‐clay model and an implicit gradient damage formulation

International Journal for Numerical Methods in Engineering, Volume 125, Issue 24, 30 December 2024.
Abstract Snow, characterized as a unique granular and low‐density material, exhibits intricate behavior influenced by the proximity to its melting point and its three‐phase composition. This composition entails a structured ice skeleton surrounded by voids filled with air and spread with liquid water.

Viscous regularization and r-adaptive remeshing for finite element analysis of lipid membrane mechanics

, 2007
As two-dimensional fluid shells, lipid bilayer membranes resist bending and stretching but are unable to sustain shear stresses. This property gives membranes the ability to adopt dramatic shape changes. In this paper, a finite element model is developed

The mixed displacement method to avoid shear locking in problems in elasticity

PAMM, Volume 24, Issue 4, December 2024.
Abstract The mixed displacement (MD) method was initially developed to mitigate geometrical locking effects in beams, plates, and shells with the intention of having intrinsically locking‐free characteristics while using equal‐order interpolation for all degrees of freedom. In other words, it is an unlocking scheme that works independent of the element
