Verification of a Fluid–Structure Interaction Model for Aortic Stenosis Through Comparison With In Vitro Experiments

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 4, April 2026.
A patient‐specific Fluid–structure Interaction (FSI) model of aortic stenosis was verified against in vitro experiments using a mock‐loop circulatory system with patient‐specific calcified and non‐calcified valve models under varying flow conditions. The in vitro experiments were replicated in the FSI model.

Displacement Reliability Analysis of Submerged Multi-body Structure’s Floating Body for Connection Gaps

Open Physics, 2019
Aiming at the problem of systems’ dynamic characteristics’ randomness caused by connection gaps of submerged multi-body structures, a stochastic and uncertainty dynamical model were formulated for connection gaps and dynamic elongation of mooring cables.

A Temporal Look at the Influence of Topographic Amplification on Earthquake‐Triggered Landslides in 3D Seismic Simulations

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Earthquakes are a primary trigger for landslides, often leading to catastrophic consequences. While numerous studies have explored the spatial distribution of earthquake‐triggered landslides, understanding the interaction between seismic waves and topography remains a critical challenge.

Damage Localisation Using a Displacement–Strain Expansion Process

Strain, Volume 62, Issue 2, April 2026.
A damage detection technique is presented using full‐field strain data derived via displacement–strain expansion. Analytical and experimental results for beam and plate structures demonstrate that the resulting damage indicator consistently identifies ‘search areas’ coinciding with actual damaged regions.

Research on Non-Random Vibration Analysis of Concrete Pump Truck Boom Based on Dynamic Excitation

Applied Sciences
When pouring concrete overhead, a pump truck boom’s vibration has a big effect on how accurately the concrete is poured. This is especially true during fixed-point pouring, where the boom’s vibration is likely to cause the pouring position to deviate ...

The Arctic Coastal Erosion Model: Overview, Developments, and Calibration at Drew Point, Alaska

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Permafrost coastlines are experiencing significant erosion as polar amplification has enhanced the effects of climate change in the Arctic. Warmer temperatures are increasing thermo‐denudation and more energetic oceans are increasing thermo‐abrasion in unlithified, ice‐bonded permafrost coastlines which comprise at least 40% of the circum ...

Probabilistic Identification of Parameters in Dynamic Fracture Propagation

International Journal for Numerical Methods in Engineering, Volume 127, Issue 4, 28 February 2026.
ABSTRACT In this paper, we propose a novel multiphase approach for identifying input parameters in dynamic fracture propagation. Often, such parameters are partially known and uncertain with incomplete input data, resulting in challenges in predicting a reliable dynamic failure response.

Why Firn Quakes

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Snow dampens sounds, but anecdotal reports concisely describe audible propagating collapse events—firnquakes—in Antarctic and Arctic snowfields. We propose combining granular and continuum mechanics to form a testable theory for conditioning, triggering, and propagation of firnquakes consistent with scarce data.

A Jacobian‐Free Newton‐Krylov Method for Cell‐Centred Finite Volume Solid Mechanics

International Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.
ABSTRACT This study proposes a Jacobian‐free Newton‐Krylov approach for finite‐volume solid mechanics. Traditional Newton‐based approaches require explicit Jacobian matrix formation and storage, which can be computationally expensive and memory‐intensive.
