Nanoindentation is a well-stablished experiment to study the mechanical properties of materials at small length scales micro and nano. Unlike conventional indentation experiments, nanoindentation response material depends on corresponding scales, such as depth, which commonly termed size effect. In current work, first, experimental observations theoretical models effect during are reviewed in case crystalline metals, focus work. Next, recent advancements visualization dislocation structure...
Abstract The PRISMS-Fatigue open-source framework for simulation-based analysis of microstructural influences on fatigue resistance polycrystalline metals and alloys is presented here. uses the crystal plasticity finite element method as its microstructure tool provides a highly efficient, scalable, flexible, easy-to-use ICME community platform. linked to different software instantiate microstructures, compute material response, assess indicator parameters. performance benchmarked against...
A computational framework is presented to include the effects of grain size and morphology in crystal plasticity finite element (CPFE) method for simulations polycrystals. The developed used investigate on yield strength extreme value fatigue response using a new grain-level length scale. Each approximated by best-fit ellipsoid, whose information modify slip resistances based Hall-Petch type relation extended each system. scale computed system shape factor proposed an earlier work discrete...
This work presents a method to incorporate the micro Hall-Petch equation into crystal plasticity finite element (CPFE) framework accounting for microstructural features understand coupling between grain size, texture, and loading direction in magnesium alloys. The effect of size texture is accounted by modifying slip resistances individual basal prismatic systems based on equation. modification endows every system at each point with system-level maximum compatibility factor, which are turn...
The three-dimensional grain-averaged response of solid bar samples under non-proportional (NP) elastoplastic axial-torsional loading was investigated using in situ high energy diffraction microscopy (HEDM) and companion crystal plasticity finite element (CPFE) modeling. Important stress metrics including applied shear (σθZ) axial (σZZ) tensor components, deviator invariants (I1, J2, J3), von Mises equivalent (), maximum resolved (mRSS), triaxiality (η), lode angle parameter () values were...
