Unique Role of Microstructure of a Bioimplant Zinc Alloy and Protein Content of Simulated Body Fluid in Corrosion and Fracture

Advanced Functional Materials, EarlyView.
BSA addition to physiological solutions enhances resistance of a Zn alloy to stress corrosion cracking (SCC) but reduces its corrosion resistance. Extended surface characterization explains the contrasting influences on corrosion and SCC. Unexpectedly, the alloy suffers transgranular SCC (TGSCC), despite extensive grain boundary precipitation. Thorough

Ductile fracture prediction in thin-walled structures through a novel damage model

Heliyon
Damage models have significantly advanced predictions of ductile fractures in large, thin-walled structures like automobiles, ships, and aircraft. However, accurately predicting these fractures remains challenging due to variations in strain localization,

Advances in 3D Bioprinting for Breast Cancer Modeling: Tumor Microenvironment, Metastasis, and Drug Screening

Advanced Healthcare Materials, EarlyView.
Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Time-frequency characteristics of acoustic emission during brittle-ductile fracture of coal under impact loading and damage extraction based on the Stockwell transform

International Journal of Mining Science and Technology
Based on the Split Hopkinson Pressure Bar (SHPB) and acoustic emission (AE) techniques, stress–strain curves, energy evolution and AE amplitude during coal failure were monitored to reveal the dynamic failure mechanism of coal under different impact ...

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

Advanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

On an isotropic damage mechanics model for ductile materials

, 2022
S.325-346A new model for combined elastoplasticity and damage is proposed. The model is based on the maximum dissipation principle and implements a strong coupling between plasticity and damage.
