Ductility Tuning via Cluster Network Characteristics of Porous Components
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

This research investigates the feasibility of 3D‐printing of a bacteriophage‐containing hydrogel made of alginate and methylcellulose. The printed hydrogels steadily release active bacteriophages for up to 35 days which is beneficial to treat implant‐associated infections.

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

A cross‐scale modeling strategy is developed to predict failure and formability of DP780 steel by linking microstructural features with macroscopic behavior. Crystal plasticity and macroscopic damage models are integrated and validated through nanoindentation, in situ bending, and finite element simulations.

Metamodeling of Void Closure during Hot Flat Rolling
This work aims to present a fast metamodel for void closure during hot flat rolling. The model takes into account every individual void of void distributions as found in industrial material and is capable of calculating the resulting void closure within only few seconds of computational time without loosing significant accuracy compared to expensive ...

Improving Constitutive Modelling of Soft Organic Clays With New Experimental Insight
ABSTRACT The engineering response of soft organic clays is controlled by anisotropy, stress history and the nature of organic matter. The behaviour of these soils has been investigated extensively over compression triaxial paths, and models are available to successfully reproduce available experimental observations. However, open questions remain about

ABSTRACT The paper presents the modelling of unsaturated soils with the material point method (MPM), including the effect of wetting leading to the loss of strength and the volumetric collapse. The elastoplastic Clay and Sand Model (CASM) extended to unsaturated conditions, formulated in terms of Bishop's stress and suction, has been implemented in an ...

A Constitutive Model Allowing for Particle Size‐Shape Coevolution
ABSTRACT This paper presents a constitutive model developed within the Continuum Breakage Mechanics (CBM) framework. The proposed model explicitly accounts for particle shape evolution during the compression of crushable granular materials. Most importantly, the proposed formulation includes a novel expression of the dissipation function that enables a

ABSTRACT Coupled nonlinear thermo‐hydro‐mechanical finite element simulations were carried out to investigate the behavior of energy micropiles subjected to thermal loading cycles. Two kinds of problems were analyzed: The case of an isolated micropile, for which comparison with previous research on medium‐size isolated energy pile is provided, and the ...
