Revisiting Graphite Electrodes for Electric Arc Furnaces: Three‐Dimensional Microstructural Heterogeneity as a Design Parameter for Fracture Resistance

open access: yesCarbon Innovation, EarlyView.
Graphite electrodes are revisited as strategically important carbon materials for electric arc furnace steelmaking. By correlating three‐dimensional microstructural complexity with fracture energy, this work reveals a fundamental trade‐off between graphitization and energy dissipation, providing a data‐driven framework for the rational redesign of ...

Adhesives with Debonding‐On‐Demand Capability: Leveraging Responsive Microcapsules for Mechanically‐Induced Debonding

open access: yesAdvanced Materials
Abstract Temporary adhesives capable of forming strong yet easily reversible bonds are garnering significant interest as sustainable materials that facilitate the recycling and recovery of high‐value components. Herein is presented a comprehensive design and parameterization framework for developing effective temporary adhesives with ...

Stable debonding at discontinuity

open access: yes, 2007
CFRP strips are used worldwide for post strengthening of concrete structures. The usual failure mode of flexural strengthening is debonding. Different descriptions and categorizations of debonding failure modes can be found in the literature, e.g..

FRP-Concrete behaviour under cyclic debonding force

open access: yes, 2007
Strengthening of concrete structures against earthquake actions is one of most important application of FRP; in particular, when strengthening interventions on beams in flexure are designed, effect of cyclic forces inducing very high bond stress regime

Modeling and experimental validation of bolt–grout bond–slip behavior for deep underground excavation support

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel shear‐lag model, validated by pull‐out tests, incorporates a constant bond stress stage to predict the complete load–displacement response of grouted rock bolts, providing a new tool for optimizing anchorage length and material toughness in deep underground engineering. Abstract The stability of rock masses in deep underground excavations, such

Investigation on the mechanical behavior of the multiple‐layered lining structure of a water conveyance tunnel with high internal water pressure

open access: yesDeep Underground Science and Engineering, EarlyView.
This study presents large‐scale similarity model testing (geometric ratio 3.6) of an innovative multiple‐layered lining system—comprising exterior precast segments, middle self‐compacting concrete, and an interior steel pipe—for high‐pressure (0.75 MPa) water conveyance tunnels.

Experimental Research on Effects of Debonding on Circular CFST Columns with Different Slenderness Ratios

open access: yes, 2019
Concrete filled steel tubular (CFST) structures have a wide range of applications in buildings and bridges due to the high bearing capacity. This beneficial composite action could be weakened even destroyed by debonding.
