Impact of Numerical Dissipation on Flow-Induced Vibration Simulation: A Comparative Study of Integration Schemes for Nonlinear Self-Excited Oscillations

Applied Sciences
Flow-induced self-excited vibration may exhibit high-frequency numerical oscillations and chaotic-like responses in long-duration simulations due to strong nonlinearity and multimodal coupling.

Nonlinear Response‐History Analyses of Masonry and Mixed Structures With HybriDFEM

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 8, Page 1694-1709, 10 July 2026.
ABSTRACT The hybrid discrete‐finite element (HybriDFEM) method, previously developed to perform static and modal analysis in discrete and coupled discrete‐finite element models, is extended to nonlinear response‐history analyses. The equations of motion for the HybriDFEM model are solved through various numerical time‐integration schemes, both explicit

General Framework for Multi‐Degree‐of‐Freedom Stiffness Matrix Updating for Iterative Solution Algorithms in Hybrid Simulation

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1947-1967, 25 July 2026.
ABSTRACT Iterative solvers are advantageous for handling nonlinear structural analysis problems. The iterative solvers often require updating the stiffness matrix, which limits their application in static and pseudo‐dynamic hybrid simulations because: (1) updating the stiffness matrix of a system involving a physical specimen is challenging; (2 ...

Assessing forest fragmentation and biodiversity impacts in sub‐Saharan Africa: Methodological challenges and conservation strategies for small‐scale agricultural landscapes

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Tropical forests in sub‐Saharan Africa (SSA) harbor around one‐third of the world's species but are becoming more fragmented due to the expansion of human settlements and small‐scale agricultural (SCA) areas. This study systematically reviewed the approaches and methods used to analyze forest fragmentation and its impact on biodiversity in SSA,

Evaluation of Modeling Assumptions for Predicting Structural Damage and Train Derailment Under Earthquake Loading

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.
ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Tree planting, natural colonisation, hybrid approaches: Land manager decisions explored

People and Nature, Volume 8, Issue 6, Page 1603-1614, June 2026.
Abstract There is a global drive to protect biodiversity and help combat climate change. In the UK, this is expressed in a number of policy initiatives and tools that include increasing tree cover as an important nature‐based solution to achieving national policy targets.

A Modified Newmark Methodology for Permanent Deformation Analysis of Rock-Fill Dams

Advances in Civil Engineering, 2018
Newmark sliding block approach has been extensively studied by many researchers in the past decades. Significant progress has been made to alleviate its deficiencies and overcome its simplifying assumptions, but some aspects such as the cyclic shear ...

Suction-induced effects on the seismic response of a zoned earth dam through simplified dynamic analyses [PDF]

E3S Web of Conferences
In zoned earth dams, the contrast in hydraulic conductivity between the core and the shells causes the saturation line to drop across the core, leaving most of the downstream shell in an unsaturated state.
