Polishing operation of a steel bar in a shear thickening fluid medium
Composites Part B: Engineering, 2019Shear thickening fluid (STF) has been utilized in several engineering applications due to its increasing viscosity under loading. Although the principal applications are protective structures and vibration attenuation systems, STF was adapted to a ...

Performance of mechanical steel bar splices using grouted couplers under uniaxial tension
, 2020In this study, grouted couplers were used to connect steel bars as an alternative approach to the conventional steel bar lapping method. The aim is to avoid bar congestion problems and to reduce the required quantity of steel bars in order to achieve the
