Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

Deep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Distortion of Digital Image Correlation (DIC) Displacements and Strains from Heat Waves

Experimental Mechanics, 2017
“Heat waves” is a colloquial term used to describe convective currents in air formed when different objects in an area are at different temperatures. In the context of Digital Image Correlation (DIC) and other optical-based image processing techniques, imaging an object of interest through heat waves can significantly distort the apparent location and ...

Influence of Adhesive Type on Heat Induced Delamination in Tension Loaded Shear Lap Cross‐Laminated Timber Samples Exposed to Radiant Heat Flux

Fire and Materials, EarlyView.
ABSTRACT Heat induced delamination (HID) is a phenomenon in engineered wood products which may result in the detachment of the bonded timber lamellae before charring propagates to the bond line interphase. This study aims to correlate the thermal degradation of two 1‐c‐polyurethane adhesives at the microscale to the thermo‐hydro‐mechanical behaviour of

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

FlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

Measurement of Super-Pressure Balloon Deformation with Simplified Digital Image Correlation

Applied Sciences, 2018
A super pressure balloon (SPB) is an aerostatic balloon that can fly at a constant altitude for an extended period. Japan Aerospace Exploration Agency (JAXA) has been developing a light-weight, high strength balloon made of thin polyethylene films and ...

Human coronary artery organ‐chip with circulating immune cells recapitulates anti‐inflammatory effect of pulsatile wall strain

Interdisciplinary Medicine, EarlyView.
A fully characterised organ‐on‐a‐chip model of the human coronary artery with endothelial and smooth muscle cells, plus circulating immune cells, created on the Emulate platform. The model successfully recapitulates the physiological effects of pulsatile vessel dilation on cell morphology and the localised inflammatory susceptibility to TNF‐α ...
