(University of Pretoria, 1965)In order to establish the rules and criteria· to be satisfied in order to develop a scale model, which may be employed to predict the dynamic behaviour of a fullscale rope-guide mineshaft installation, the theory of the ...
-
(University of Pretoria, 1976)Die onbevredigende konsep van die interne wrywingskoeffisient wat as basis dien vir numeries-bruikbare fraktuurkriteria vir brosmateriale, onder andere die van Coulomb-Mohr, impliseer dat daar meriete in die kriteria ...
-
(University of Pretoria, 1990)In the first two chapters of this thesis, the novel method, developed by Mathews and Richards1, for predicting the thermal performance of buildings is introduced. The further enhancement and theoretical clarification of ...
-
(University of Pretoria, 1993)To assist in the development of mechanical structures which are subjected to dynamic loads, structural dynamic testing, using a test rig loaded by servo-hydraulic actuators to reproduce operational measured responses ...
-
(University of Pretoria, 1997)Practicing engineers need an integrated building, HVAC and control simulation tool for optimum HVAC design and retrofit. Various tools are available to the researchers, but these are not appropriate for the consulting ...
-
(University of Pretoria, 1997)Damage in structures may be identified and quantified by using measured frequency response functions (FRFs) or identified modal properties as a basis for updating. The main shortcoming of these methods is that if they ...
-
(University of Pretoria, 1999)In this thesis, techniques for testing aircraft models in ground effect in a low speed wind tunnel are investigated. Although these types of tests have been done before, the current study is unique in that forces are ...
-
(University of Pretoria, 1999)In this study, experimental tests and Computational Fluid Dynamics are used to investigate the aerodynamic performance of two types of track-based racing cars. After the literature study, where automotive aerodynamics is ...
-
(University of Pretoria, 2000)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2002)Underground pipelines are used in various process piping systems to transport gasses or fluids and are usually subjected to the effects of external corrosion. Corrosion can be defined as the deterioration of a material due ...
-
(University of Pretoria, 2003)This study is concerned with the design of vehicle structures through the use of Fatigue Equivalent Static Loads (FESL). A large percentage of failures of mechanical structures can be attributed to fatigue. Furthermore, ...

(University of Pretoria, 2004)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2004-08-03)Paper machine sheet dewatering by roll pressing is critical in the establishment of uniform moisture profiles, as well as other mechanical properties of the paper during manufacture. Roll cover profiles are maintained ...
-
(University of Pretoria, 2005)Owing to the crippling nature of arthritis, surgeons have been trying for well over a century to successfully treat this debilitating disease particularly when attacking the hip joint. In the early 1970s, Sir John Charnley ...
-
(University of Pretoria, 2005)Conventional gearbox vibration monitoring techniques are based on the assumption that changes in the measured structural response are caused by deterioration in the condition of the gears in the gearbox. However, this ...
-
(University of Pretoria, 2005)Mine haul road maintenance is traditionally done at scheduled intervals or after regular inspection. Both these methods can lead to unwarranted expenditure, either through over-maintaining the road, or failure to recognise ...
-
(University of Pretoria, 2005)The modern gas turbine engine industry needs a simpler and faster method to facilitate the design of gas turbine combustors due to the enormous costs of experimental test rigging and detailed computational fluid dynamics ...
-
(University of Pretoria, 2006)The implementation of finite element methods (FEM) for fatigue analysis of complex structures in industry are becoming an increasingly effective and accepted practice. In the case of large plate-like structures, such as ...
-
(University of Pretoria, 2006-01-11)It is argued that together with improved protection structures and energy dissipation systems, a favourable pilot position with sufficient support and restraint could reduce fatalities in aviation accidents. In this document ...
-
(University of Pretoria, 2006-01-13)The analysis and optimum design of stiffened, shear webs in aircraft structures is addressed. The post-buckling behaviour of the webs is assessed using the interactive algorithm developed by Grisham. This method requires ...
