Ujjaini Kempaiah, K. (author)A flying aircraft consumes fuel to overcome air resistance during its motion. A significant part of this consumption (55%) is due to turbulent skin friction arising at the interface of the aircraft surface and the air. The current work aims to develop and investigate relevant turbulent skin-friction reduction techniques and assist in advancing...doctoral thesis 2023

van Dam, Nathalie (author)Propulsion power is an important metric in wheelchair racing. For a flat surface, it can be estimated from the sum of friction power and kinetic power. Usually, to determine friction power, the rolling and air drag coefficient first need to be determined with coast-down tests or other time-consuming methods. The aim of this paper was to...master thesis 2023

MAHAJAN, SAURABH (author)Structural joints influence the design strength, material requirement of a structure. Structural joints experience damping dissipation due to friction damping or hysteresis damping. Damping is often used for reducing the vibrations in a structure. However, large amount of energy dissipation leads to deterioration of the material used for...master thesis 2023

van Delft, Youri (author)Background: Through technological development, a variety of mechanical finger joints have been produced. No current design takes inspiration from nature enough to develop a synovial inspired single finger joint. Due to this the potential performance is unknown, while natural joints out perform mechanical finger joints with respects to the...master thesis 2023

Schuijt, Rinus (author)In this thesis, the friction performance of polyurethane tensioner pads used in offshore pipe-laying was investigated. Tensioner pads are used in pipe-lay to create tension in a pipe. The need to understand the pads better is because of the increased use of pipe coatings and pipe lay in deeper waters. Deep water leads to more pipe tension, and...master thesis 2023

Monnoyer, Jocelyn (author), Willemet, L. (author), Wiertlewski, M. (author)Shortly after touching an object, humans can tactually gauge the frictional resistance of a surface. The knowledge of surface friction is paramount to tactile perception and the motor control of grasp. While potent correlations between friction and participants' perceptual response have been found, the causal link between the friction of the...journal article 2023

Wang, Bin (author), Wang, Di (author), Hicks, M.A. (author), Feng, Xia Ting (author)Retrogressive failures occur in slopes consisting of sensitive materials such as snow or quick clay. They can be triggered by a small disturbance at the slope toe, but can cause propagated failure spreading miles away. Understanding the physical mechanism and predicting the retrogressive failure process are particularly important. Previous...journal article 2023

Li, Chutian (author), Lai, F. (author), Shiau, Jim (author), Keawsawasvong, Suraparb (author), Huang, Hanhui (author)A narrow backfill zone is formed when retaining walls are built near existing stabilized structures (e.g., rock faces). In such circumstances, the classical passive earth pressure coefficient is no longer applicable, and a correction factor is required for the design. This paper aims to develop analytical solutions for estimating the passive...journal article 2023
