Independent assessment and benchmarking of no/low cost finite element analysis software for linear and non/linear static structural analysis.
(2016)The aim of this research was to determine if the development of low-cost (less than 500 USD) or no-cost analysis software, specifically in the area of computational structural mechanics through finite element analysis ... -
Influence of concentration on properties of spray deposited nickel oxide films for solar cells.
(Elsevier., 2017)Spray pyrolysis technique was used to deposit various concentration of nickel oxide films on glass substrate. The Effect of varying precursor concentration on elemental, morphological and structural properties was ... -
The influence of process factors on the production of semi solid feedstock.
(2000)Semi-solid manufacturing is a near net shape forming process that takes advantage of an alloy's thixotropic behaviour. However, in order to obtain the desired thixotropic properties from an alloy in the semi -solid state, ... -
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 ... -
Influence of wagon structure on the vertical response of freight.
(2002)Historically, wagons have been designed according to the American Association of Railroads specifications. These require that wagons be designed to withstand a static load between the couplers of 350 tons. This implies ... -
Investigation and design of wet-mill equipment and process technology.
(2003)need to dry-mill the wheat into flour, and as a result, the total cost of conversion from wheat to bread is reduced. The resulting product has been perceived as being more filling than normal bread and it is also more ... -
Investigation and development of structural composite materials for use as electromagnetic shielding agents in the current aerospace industry.
(2010-10-20)Due to the nature of today's competitive electronics market, the development of new electronic -
Investigation into inspection system utilisation for advanced manufacturing systems.
(2017)Varied inspection is an aperiodic inspection utilisation methodology that was developed for advanced manufacturing systems. The inspection scheme was created as a solution to improve manufacturing performance where inspection ... -
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 ... -
An investigation into the performance of plasma and laser coatings under rolling contact.
(2008)Rolling contact is experienced by a large number of components in mechanical designs. Examples include roller bearings and ink distribution rollers in the printing industry. Rolling contact results in surface wear. It is ... -
An investigation of solar powered absorption cooling systems for South Africa.
(2012)Increased standards of living and indoor comfort demands have led to an increase in the demand for air-conditioning in buildings in South Africa. Conventional vapor compression systems use refrigerants that damage the ... -
An investigation of the strength of an aircraft wing bolt with a centrally drilled hole.
(2000)The investigation contained herein is a part of a larger, long-term project: The Development of SMART Aircraft Bolts. Structural failures, at highly stressed components, arc common in some of the aircraft used by the ... -
Investigation of the thermophysical properties of coconut fibre based green nanofluid for heat transfer applications.
(2018)Significant resources are being channelled toward research on carbon nanomaterials obtained from biomass precursors because of their overall environmental acceptability, stability, low toxicity and simplistic use. Due ... -
Life prediction of power line damper.
(2012)Power line function is to transfer electrical power. Power lines represent a major component in the transport process of electricity and they are subjected to various types of failures. Causes of failure include wind-induced ... -
Lightweight structural design of UAV wing through the use of coreless composite materials employing novel construction techniques.
(2017)A new structural layout was designed for an existing UAV wing with the aims of lightening the wing by eliminating the use of cored composite construction and reducing the manufacturing time of the wing by making use of ... -
Long term adherence to antiretroviral therapy in a South African cohort.
(2018)Background Current treatment of HIV requires life-long antiretroviral therapy (ART) to suppress HIV replication. Adherence to medication is a critical component of treatment success, where ≥95% of doses, must be taken ... -
