Effect of crack depth and specimen width on fracture toughness of a carbon steel in the ductile-brittle transition region [PDF]
, 2000 The effects of crack depth (a/W) and specimen width W on the fracture toughness and ductile±brittle transition have been investigated using three-point bend specimens.

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments
Advanced Functional Materials, EarlyView.We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

The ductile to brittle transition behavior in a Zr-based bulk metallic glass
, 2015 The ductile to brittle transition (DBT) of crystalline metals and alloys has been extensively studied in scientific and engineering fields. However, the DBT of non-crystalline metals and alloys such as bulk metallic glasses (BMGs) remains poorly ...

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces
Advanced Functional Materials, EarlyView.Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Brittle-ductile transition in coal pillar failures
, 2023 Factor of Safety (FoS) is the most widely used empirical criterion in coal pillar design. The increased vertical stresses associated with deep mining are resulting in pillar sizes much larger than those used in the development of the empirical strength ...

Toughness by design: multi-scale interpenetrating lattices with size-enhanced fracture resistance
npj MetamaterialsArchitecture has long been used as a tool to enhance material toughness, but despite extensive research dedicated to studying toughening mechanisms, the role of feature size remains poorly understood.

THE BRITTLE-TO-DUCTILE TRANSITION IN GERMANIUM
, 1994 The brittle-to-ductile transition in precracked germanium crystals has been studied experimentally. Germanium undergoes a "smooth" brittle-ductile transition, where the stress to fracture rises steadily with temperature, associated with dislocation ...

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 ...
