Strain gradient polycrystal plasticity for micro-forming [PDF]
AIP Conference Proceedings, 2016 The developments in the micro-device industry has produced a substantial demand for the miniaturized metallic components with ultra-thin sheet materials that have thickness dimensions on the order of 50-500 µm which are produced through micro-forming processes.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Energetic Approach to Large Strain Gradient Crystal Plasticity
Acta Polytechnica, 2012 We formulate a problem of the evolution of elasto-plastic materials subjected to external loads in the framework of large deformations and multiplicative plasticity.

Strain Gradient Plasticity Analysis of Amorphous Plasticity
Procedia Structural IntegrityAmorphous materials lack a defined crystalline structure, exhibiting a disordered atomic arrangement that imparts superb mechanical properties and great potential for applications in many areas. Because of their disordered nature, metallic glasses exhibit dramatically different deformation behaviours than crystalline materials.

Advanced Engineering Materials, EarlyView.In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Photosynthetic traits of Phragmites australis along an ecological gradient and developmental stages
Frontiers in Plant ScienceCommon reed (Phragmites australis) is a cosmopolitan species, though its dieback is a worldwide phenomenon. In order to assess the evolutionary role of phenotypic plasticity in a successful plant, the values and plasticity of photophysiological traits of

Advanced Engineering Materials, EarlyView.Plasma‐assisted hybrid friction stir welding of dissimilar AlCu joints employs localized plasma preheating to balance heat input and enhance plastic flow. The optimized process reduces axial force by up to 35%, refines the microstructure, and achieves ≈96% joint efficiency.
