Glimpse from 10 Years of Arctic Materials R&D
A data management system for material properties and fracture assessment at low temperature
A Data Management System for Material Properties and Fracture Assessment at Low Temperature
Based on the project Arctic Materials (2008-2017), a generic database platform has been developed for efficient access to material data of various materials, such as steels/weldments, aluminium alloys, composites and polymers/coatings. Safe and flexible data processing, accessible through a customiz...
Multiscale modeling of cemented tungsten carbide in hard rock drilling
Wear of cemented tungsten carbide percussive drill?bit inserts: Laboratory and field study
A micromechanical constitutive modeling of WC hardmetals using finite-element and uniform field models
Experimental and numerical study of drill bit drop tests on Kuru granite
This paper presents an experimental and numerical study of Kuru grey granite impacted with a seven-buttons drill bit mounted on an instrumented drop test machine. The force versus displacement curves during the impact, so-called bit–rock interaction (BRI) curves, were obtained using strain gauge mea...
Experimental and numerical study of Kuru granite under confined compression and indentation
The paper presents an experimental and numerical investigation on the response of Kuru granite rock under confining compression and static indentation. Triaxial compression tests were executed at different levels of confining pressure. Indirect tensile tests were carried out with Brazilian disks, an...
Effects of strain rate and confining pressure on the compressive behavior of Kuru Granite
Understanding the influence of hydrostatic pressure and loading rate on the strength and fracture behavior of rocks is very important for the development of deep drilling technology. This paper presents a systematic study on the mechanical properties and behavior of Kuru Gray granite at confining pr...
