Influence of Deviatoric Stress on the Deformation and Damage Evolution of Surrounding Rock under Unloading Conditions

open access: yesShock and Vibration, 2020
The study of the deformation and damage evolution behaviour of surrounding rock under excavation unloading conditions is of vital importance for a deep understanding of the mechanism of roadway failure.

Investigation of fiber/matrix adhesion: test speed and specimen shape effects in the cylinder test [PDF]

open access: yes, 2013
The cylinder test, developed from the microdroplet test, was adapted to assess the interfacial adhesion strength between fiber and matrix. The sensitivity of cylinder test to pull-out speed and specimen geometry was measured.

Optimising the performances of hollow antiresonant fibres [PDF]

open access: yes, 2011
We study the loss of novel antiresonant hollow-core fibres, demonstrate the existence of a wavelength independent optimum distance between core-surround and solid outer cladding, and provide useful guidelines for the fabrication of practical low-loss ...

New Hollow Cylinder Torsional Apparatus (HCTA) [PDF]

open access: yes, 2003
Many geotechnical problems involve the rotation of principal stress and strain directions in the ground. To assess the fundamental behaviour of soils under such conditions, a Hollow Cylinder Torsional Apparatus (HCTA) with independent controls and ...

Energy Absorption Capacity of Bio-Inspired Honeycomb Integrated Beetle Elytron Plates

open access: yesEngineering Proceedings
Growth in the advancement of 3D printing technology has made it easy to fabricate complicated bio-inspired structures (BISs). In this paper, the sandwich structure of the beetle elytron structure (BES) hollow cylinder, influencing every corner of the ...

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

A borehole stability study by newly designed laboratory tests on thick-walled hollow cylinders

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2015
At several mineral exploration drilling sites in Australia, weakly consolidated formations mainly consist of sand particles that are poorly bonded by cementing agents such as clay, iron oxide cement or calcite. These formations are being encountered when

Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization

open access: yesAdvanced Functional Materials, EarlyView.
Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature
