Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Numerical modelling of hydraulic fracturing in naturally fractured rock
, 2018 This thesis presents a novel approach for hydro-geomechanical modelling of fractured rocks by linking a solid mechanics model with a multi-fluids and multi-phase fluid flow model using the immersed-body approach for coupling fluids and solids. The method uses conservative mesh-to-mesh projection to pass variables between an mesh adapting multi-phase ...

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing
Advanced Engineering Materials, EarlyView.The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Experimental Determination and Numerical Calculation of Fracture Viscosity Criterion (J-integral)
Наука и техника, 2005 The paper shows that it is necessary to accept energy J-integral criterion as a criterion of fracture viscosity under conditions when the zone of plasticity is rather large at crack top.

Advanced Engineering Materials, EarlyView.The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Fatigue Crack Initiation and Growth in Nanocrystalline Ni at Multiple Length‐Scales
Advanced Engineering Materials, EarlyView.Overview of miniaturized in situ SEM fatigue setup and resultant fatigue crack growth data for nanocrystalline Ni. The presented study focuses on the analysis of fatigue crack growth rate (FCGR) in focused ion beam‐notched microcantilevers prepared from nanocrystalline (NC) Ni as a model material.

A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science
Advanced Engineering Materials, EarlyView.We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Numerical Modelling of Settlement Compensation by Means of Fracture Grouting
Soils and Foundations, 2004 Displacement grouting is increasingly used as a corrective measure to control settlements of buildings induced by near surface excavations such as tunnelling (compensation grouting) or when structures have to be re-levelled because unacceptable (differential) settlements have occurred (corrective grouting).
