Multi-Scale evaluation of low-temperature performance in asphalt mixtures using not-notched semi-circular bending creep testing

Frontiers in Materials
To address the challenge of obtaining core samples directly from the field for low-temperature crack resistance tests of asphalt mixtures, this study utilizes the not-notched semi-circular bending (NN-SCB) creep test as a novel evaluation method.

Analysis on seismic performance of a new type of stiffening rib angle steel damper [PDF]

E3S Web of Conferences
This paper proposes a stiffening angle steel damper for beam-column joints. The ABAQUS software is used to study the influence of the thickness, opening ratio and number of openings of the stiffening rib on the energy dissipation performance of the ...

Inflammatory Response‐Inspired Thermochromic Shield for Pneumatic Structures

Advanced Engineering Materials, EarlyView.
A thermochromic shield for pneumatic structures is developed, using anhydrous sodium acetate powder and thermochromic pigment‐included solution. In this shield composed of three layers, the exothermic and thermochromic reactions, followed by the mixture of both components, occur promptly with an incident of penetrating damage as a sign of initial ...

Atmospheric Boundary Layer Turbulence in the Presence of Swell: Turbulent Kinetic Energy Budget, Monin–Obukhov Similarity Theory, and Inertial Dissipation Method

Journal of Physical Oceanography, 2020
Turbulence over the mobile ocean surface has distinct properties compared to turbulence over land. Thus, findings that are based on the turbulent kinetic energy (TKE) budget and Monin–Obukhov similarity theory (MOST) over land may not be applicable to ...

Influence of Sample Preparation and Processing Procedures on the Thermal Diffusivity of MgO‐C Refractories

Advanced Engineering Materials, EarlyView.
The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Particle rotations and energy dissipation during mechanical compression of granular materials

Journal of the mechanics and physics of solids, 2019
We present new in-situ measurements of particle rotations and energy dissipation during compression of 3D packings of stiff, frictional particles. Two confined, uniaxial compression tests with different degrees of lateral confinement are discussed. X-ray

Damage mechanisms of interlayer rock mass under close-distance coal seam mining disturbance: a macro-micro scale study

Results in Engineering
Rock mass damage induced by close-distance coal seam mining significantly affects roadway surrounding rock stability. Current research inadequately addresses macroscopic and mesoscopic damage characteristics of rocks under multi-stage mining stress paths.

Four‐Point Bending Tests at High Temperatures on Commercial MgO‐C Refractory Bricks with and Without Recyclate Considering Different Carbon Contents

Advanced Engineering Materials, EarlyView.
Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
