High temperature fatigue crack growth behaviour of TIMETAL 21S in an oxidizing environment.
(1995)
The high temperature fatigue crack growth behaviour of the newly developed, metastable titanium-based alloy, TIMETAL 21S, was investigated in an inert and an oxidizing environment. The investigation adopted a two pronged ...
The performance of a one and a half stage axial turbine including various tip clearance effects.
(1993)
The necessary clearance at the tip of unshrouded rotors of axial turbines allows fluid
to leak from the pressure to the suction side of the blade and produces an important
component of loss that is ultimately responsible ...
The effect of tip clearance and tip gap geometry on the performance of a one and a half stage axial gas turbine.
(1996)
In a previous work of a similar nature, the performance of a low speed axial turbine with
a second stage nozzle was examined with respect to the effect of the variation of tip
clearance for various tip shapes. Present ...
Non-stationary responses on hoisting cables with slowly varying length.
(1999)
Cables in hoisting installations, due to their flexibility, are susceptible to vibrations. A common arrangement in industrial hoisting systems comprises a driving winder drum, a steel wire cable, a sheave mounted in headgear, ...
Modelling saturated tearing modes in tokamaks.
(1992)
In this thesis a model for saturated tearing mode islands is developed. The equations for
the mode amplitudes are essentially those of R B White et al,after a pertubation
expansion has been made. It is well known that ...
Investigation into on-line optimization of cutting tool geometry.
(1996)
Metal cutting is an important process used to
manufacture components with machined surfaces or holes.
Due to the wide usage o f this manufacturing process,
research with the aim to optimize the cutting processes
is ...
The influence of sulphidizing attack on the mechanism of failure of coated superalloy under cyclic loading conditions.
(1998)
A systematic study of the effect of sulphidizing atmosphere on the High Temperature Low
Cycle Fatigue (HTLCF) properties of coated and uncoated unidirectionally solidified MARM002
nickel base superalloy was performed at ...
Analysis and design optimization of laminated composite structures using symbolic computation.
(1994)
The present study involves the analysis and design optimization of thin and thick laminated composite structures using symbolic computation. The fibre angle and wall thickness of balanced and unbalanced thin composite ...
Communication, mapping and navigational aspects for a free-ranging, automated guided vehicle.
(1992)
A free-ranging automated guided vehicle incorporating navigation and radio communication for use in a fully automated flexible manufacturing system has been developed. A vehicle, operating as a complete subsystem, was built ...
Optimisation of the process parameters of the resin film infusion process.
(1999)
The resin film infusion process or RFI is a vacuum assisted moulding method for producing high quality fibre reinforced components. The goals of this research have been to investigate this new process, with the aim of ...
