Low‐Velocity Impact Response of Nacre‐Inspired E‐Glass/Epoxy Composites With Varying Platelet Sizes

Polymer Composites, Volume 47, Issue 3, Page 2781-2798, 10 February 2026.
Impact response of nacre‐inspired E‐glass/epoxy composites with different platelet sizes. ABSTRACT This study explores the low‐velocity impact behavior of nacre‐inspired biomimetic platelet composites (NIBPC), using low‐cost E‐glass fiber in chopped strand mat (CSM) form as reinforcement and epoxy resin as the matrix.

Benchmarking Organic Photodiodes at the Noise Floor

Advanced Optical Materials, Volume 14, Issue 6, 9 February 2026.
A precise measurement framework based on a calibrated, ultra‐low‐noise automated setup with open‐source Python scripts enables accurate benchmarking of photodiodes. The unique combination of time‐dependent current measurement under dark conditions, followed by continuous‐wave faint illumination, facilitates reliable extraction of photocurrent near ...

Apparatus Design and Finite Element Modeling for Controlled‐Speed Nakazima Experiments

Engineering Reports, Volume 8, Issue 2, February 2026.
This study has two primary aims: first, to design a scaled device with deformable tooling components that can conduct Nakazima experiments with a rotating tool, and second, to develop a 3D Finite Element model for scaled Nakazima‐test simulation considering deformable tooling components.

Study on Key Controlling Factors of Fracture Propagation by Shaped Charge Blasting in Coal Seams

Energy Science &Engineering, Volume 14, Issue 2, Page 721-736, February 2026.
Gas drainage is the fundamental approach to controlling gas disasters in coal mines. For single low‐permeability coal seams, it should be supplemented by coal seam permeability enhancement technologies to improve gas drainage efficiency. This paper conducted a numerical simulation study on the key controlling factors affecting the fracturing effect of ...

Pulmonary Obstruction and Age, Not Activity, Associate With Muscle Oxidative Impairment in Smokers With and Without COPD

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background Low muscle oxidative capacity is an extrapulmonary manifestation of chronic obstructive pulmonary disease (COPD) with unclear aetiology. We sought to characterize locomotor muscle oxidative capacity in never smokers and ever smokers with and without COPD and determine clinical and behavioural features associated with low muscle ...

Long-term geomechanical behavior of geogrid-reinforced ballast in dynamic triaxial tests

Soils and Rocks
During operation, the ballast is subjected to a gradual breakage process that causes clogging of the substructure. Intervention periods on the ballast layer generate high costs that impact the long-term competitiveness of railways. In this context, this work aims to evaluate the geomechanical behavior of reinforced ballast, assessing the effect of ...

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 597-612, 10 February 2026.
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

Bearing Capacity of Tension Steel Piles in Thinly Inter‐Layered Soils: Numerical Class‐A Prediction vs. Field Measurements

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 3, Page 1430-1450, 25 February 2026.
ABSTRACT This study investigates the bearing capacity of tension piles and pile‐soil interaction during loading. Discrepancies between predicted and measured bearing capacities in previous tests motivated the study, where analytical methods showed considerable scatter and uncertainties in design.
