Fish Scales: A Multifunctional Biomaterial from Nature
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.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 ...

Evaluation of volumetric strain quantities and types of volumetric strain curves under failure-deformation process of hard brittle rocks [PDF]
, 2018 Purpose. The aim of this work is to show whether or not a relationship exist among the different volumetric strain quantities and to assess also whether the volumetric quantities are related to the different types of volumetric strain curves under ...

steel research international, EarlyView.This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...

Microstructural modelling of creep crack growth from a blunted crack [PDF]
, 1998 The effect of crack tip blunting on the initial stages of creep crack growth is investigated by means of a planar microstructural model in which grains are represented discretely. The actual linking-up process of discrete microcracks with the macroscopic

Gramian-based optimal design of a dynamic stroke amplifier compliant micro-mechanism. [PDF]
, 2007 International audienceThis paper presents a new method developed for the optimal design of microrobotic compliant mechanisms. It is based on a flexible building block method, called FlexIn, which uses an evolutionary approach, to optimize a truss-like ...

steel research international, EarlyView.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 ...
