Axial fatigue behaviour of additively manufactured tool steels

Author: Tshabalala, Lerato C ; Sono, Oscar JH ; Makoana, Nkutwane W ; Masindi, J ; Maluleke, O ; Johnston, C ; Masete, Mosimanegape S Date: Jun 2020 Tool steels contain high-nickel and low-carbon content, consisting of alloying elements such as Ni, Co, Mo, Ti and Al. These tool steels exhibit excellent mechanical properties combining high strength with good toughness. The aim was to study ... Read more
Caltrans accelerated pavement testing (CAL/APT) program - test results: 1993-1996

Author: Nokes, WA ; Harvey, JT ; Du Plessis, L ; Long, F ; Stolarski, PJ Date: Aug 1997 By combining the results of both the HVS and laboratory tests, interpretations of pavement performance are described and recommendations for pavement design and construction have been made to Caltrans. Read more
Effect of laser shock peening on fatigue life at stress raiser regions of a high-speed micro gas turbine shaft: A simulation based study

Author: Pretorius, JG ; Desai, DA ; Snedden, Glen C Date: Nov 2019 Fatigue failure due to stress raiser regions on critical rotating components in gas turbine engines, such as the shaft, is a crucial aspect. Methods to reduce these stresses and improve fatigue life are a source of ongoing research. Laser ... Read more
Fatigue and rutting performance of conventional asphalt and bitumen-rubber asphalt under accelerated trafficking.

Author: Rust, FC ; Harvey, JT ; Verhaeghe, Benoit MJA ; Noakes, W ; Van Kirk, J Date: Oct 1994 The Californian Department of Transportation commissioned a pilot project to evaluate the potential of the Heavy Vehicle Simulator (HVS) for conduction pavement studies. The effect of channelisation of traffic on the rutting behaviour of a ... Read more
Laboratory investigation of the performance properties of hot mix asphalt containing waste glass

Author: Anochie-Boateng, Joseph ; George, TB Date: Jul 2016 CSIR is currently undertaking a study on potential utilization of crushed glass as a substitute material to natural aggregate in asphalt mixes. As part of the study, laboratory investigation is needed to determine the performance characteristics ... Read more
Laser shock peening on a 6056-T4 aluminium alloy for airframe applications

Author: Glaser, D ; Polese, C ; Bedekar, RD ; Plaisier, J ; Pityana, Sisa L ; Masina, Bathusile N ; Mathebula, T ; Troiani, E Date: Mar 2014 Laser Shock Peening (LSP) is a material enhancement process used to introduce compressive residual stresses in metallic components. This investigation explored the effects of different combinations of LSP parameters, such as irradiance ... Read more
Measuring and controlling the mining environment for worker health and safety

Author: Pretorius, C Date: Oct 2012 This presentation discusses the work on lung disease silicosis and other work conducted by the human factors group as well as the services offered by the laboratory. Read more
Wake up to fatigue risk management

Author: Schutte, PC Date: Jun 2009 There have been several high-profile accidents in industry where fatigue was identified as either causal or contributory. The risk of fatigue is inherent in any worktime arrangement involving shift work, long hours of work, irregular hours, ... Read more
