Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Creep Performance of Stainless Steel 316 Brackets: Insights From Conventional and Advanced Modeling Approaches

steel research international, Volume 97, Issue 9, Page 4889-4904, September 2026.
Creep behavior of SS 316 brackets is examined through experiments, conventional creep laws, and advanced constitutive modeling. Long‐term deformation, stress redistribution, and life prediction are compared under service‐relevant loads. The study highlights the limits of classical models and demonstrates improved accuracy using advanced approaches for ...

4D imaging of a porous carbonate rock under triaxial loading: quantitative correlation between local porosity and strain

Journal of Synchrotron Radiation, Volume 33, Issue 5, Page 1509-1521, September 2026.
A 4D X‐ray computed tomography experimental campaign was carried out on a porous carbonate rock to investigate the link between initial porosity and deformation modes. This paper presents the experiment and the methods used to explore this relationship.The study of the mechanical behaviour of carbonate rocks has benefited from the evolution of ...

Time‐dependent (Creep) Compaction in Volcanic Rocks

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Porous volcanic rocks form volcanic edifices and host key geothermal reservoirs worldwide. When subjected to constant stress above dilatancy in the brittle regime, these materials undergo time‐dependent failure known as brittle creep. In the ductile regime, where deformation is compactive, time‐dependent compaction—compaction creep—has been ...

Calculation of watershed flow concentration based on the grid drop concept

Water Science and Engineering, 2008
The grid drop concept is introduced and used to develop a micromechanism-based methodology for calculating watershed flow concentration. The flow path and distance traveled by a grid drop to the outlet of the watershed are obtained using a digital ...

Micromechanics of Alveolar Edema [PDF]

American Journal of Respiratory Cell and Molecular Biology, 2011
Abstract The decrease of lung compliance in pulmonary edema underlies ventilator-induced lung injury. However, the cause of the decrease in compliance is unknown. We tested the hypothesis that in pulmonary edema, the mechanical effects of liquid-filled alveoli increase tissue stress in adjacent air-filled alveoli.

Theoretical and Practical Implications Derived From the Formulation of the Theory of Critical Distances

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2610-2618, July 2026.
ABSTRACT The Theory of Critical Distances comprises several methodologies that allow fracture, fatigue, and stress corrosion cracking phenomena to be analyzed. Such methodologies are usually referred to as the Point Method (PM), the Line Method (LM), the Area Method (AM), and the Volume Method (VM).
