Final Report Factors Influencing Stability of Granular Base Course Mixes

open access: yes, 1991
To evaluate the various factors influencing the stability of granular base course mixes, three primary goals were included in the project: (1) determination of a suitable and realistic laboratory method of compaction; (2) effect of gradation, density

Computer Simulation of Granular Materials

open access: yesComputing in Science & Engineering, 2009
What are granular materials, and how can we generate them on computers? How does a granular pile respond to an external force? The author attempts to answer such questions by reviewing a range of granular material theories and numerical simulation techniques.

Numerical Dynamics of Granular Materials [PDF]

open access: yes, 2002
Contact Dynamics is a numerical method, suitable for computing the dynamical motion of large collections of rigid bodies, with Coulomb friction taken into account in the event of contact. The principles of the method are sketched, in particular the way possible collisions or other nonsmooth features of the evolution are handled.

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

The geotechnical behaviour of ballast materials for railway track maintenance [PDF]

open access: yes, 2004
The search for an improved mechanised method of maintaining railway track to the correct level and alignment led to the development of the stoneblower, a machine that lifts the rail and attached sleepers and pneumatically injects the required amount of ...

Pore Structure of Grain-Size Fractal Granular Material

open access: yes, 2019
Numerous studies have proven that natural particle-packed granular materials, such as soil and rock, are consistent with the grain-size fractal rule. The majority of existing studies have regarded these materials as ideal fractal structures, while few ...

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

open access: yesAdvanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing
