Extending intergranular normal-stress distributions using symmetries of linear-elastic polycrystalline materials
Samir El Shawish
Izvirni znanstveni članek
Oznake: polikristalni materiali;distribucije INS;linearnoelastična zrna;linear-elastic material;INS distributions;polycrystalline materials;
Intergranular normal stresses (INS) are critical in the initiation and evolution of grain boundary damage in polycrystalline materials. To model the effects of such microstructural damage on a macroscopic scale, knowledge of INS is usually required statistically at each representative volume element ...

Analytical model for predicting induced-stress distributions in polycrystalline materials
Timon Mede, Samir El Shawish
Izvirni znanstveni članek
Oznake: polikristalini;mikromehansko modeliranje;bikristalni modeli;
grain-boundary-stress distributions induced by the uniform external loading (in the elastic strain regime). Such statistical knowledge of local stresses is a necessary prerequisite to assess the probability for intergranular cracking initiation. Model predictions are verified through finite element ...

Fast Fourier transform approach to strain gradient crystal plasticity
Amirhossein Lame Jouybari, Samir El Shawish, Leon Cizelj
Izvirni znanstveni članek
Oznake: strain localization A;strain gradient crystal plasticity B;polycrystalline material B;FFT-homogenization method C;
The Strain Gradient Crystal Plasticity (SGCP), based on cumulative shear strain, is developed to regularize and simulate the size effect behavior of polycrystalline aggregates, specifically in the formation of localization bands in terms of slip and kink bands, influenced by strain softening during ...

Enhanced strain gradient crystal plasticity theory
Amirhossein Lame Jouybari, Samir El Shawish, Leon Cizelj
Izvirni znanstveni članek
Oznake: jedrska tehnika;polikristalini;
An Enhanced Strain Gradient Crystal Plasticity (Enhanced-SGCP) theory, based on the quadratic energy contribution of the Nye tensor, is developed within a thermodynamically consistent framework to accurately capture shear band formation in terms of slip and kink bands within the microstructure. The ...

Dynamics of Taylor bubble interface in vertical turbulent counter-current flow
Jan Kren, Boštjan Zajec, Iztok Tiselj, Samir El Shawish, Žiga Perne, Matej Tekavčič, Blaž Mikuž
Izvirni znanstveni članek
Oznake: slug flow;Taylor bubble;interfacial waves;
Dynamics of the Taylor bubble interface in the vertical counter-current flow was analyzed with video recordings at 100 – 800 frames per second. Taylor bubbles in air-water mixture were studied on time intervals of up to several minutes in stagnant conditions, where buoyancy is dynamically balanced b ...
