AUTO-SHAPE ANALYSIS OF IMAGE TEXTURES IN FRACTOGRAPHY
Image Analysis and Stereology, 2011 The aim of this study is to estimate the velocity of fatigue crack growth (crack growth rate - CGR) from the texture in SEM images of crack surfaces. A simple and quick method is based on fitting training images as a linear combination of several small ...

Polymer Composites, Volume 47, Issue 19, Page 17076-17090, 10 October 2026.Comparison of powder impregnation and hybrid commingled non‐wovens for PA6/rCF nonwoven composites. The two‐step powder route gives lower voids and higher properties, while the single‐step hybrid route is limited by precursor inhomogeneity and high void content.

Fatigue life of high strength steel for cold forming
Metalurgija, 2017 The article presents the results of fatigue tests carried out on STRENX-type high-strength cold forming steel. For high-cycle fatigue tests carried out using low cycle loading frequencies of around 30 Hz, a ROTOFLEX machine was used. For ultra high-cycle

Fractography of Long Bones with High-Velocity Projectile Trauma
, 2020 Previous studies of bone fractography have examined only cases of blunt trauma. Here we assess whether fracture surface features are also found on bones subjected to high-velocity projectile trauma. Civil War–era long bones were assessed for the presence

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Carbides strengthen the grain boundaries; nevertheless, excessive carbide precipitates embrittle the grain boundaries of high‐temperature alloys during prolonged service. Here, we provide direct evidence of solute rare‐earth atoms and demonstrate that they can trap vacancies and inhibit interstitial diffusion, restraining carbide precipitation
