Efficacy of the inherent strain method for residual stress determination of additively manufactured IN718 selective laser melted specimens
(North-West University (South Africa)., 2022)
Selective laser melting (SLM) is an additive manufacturing (AM) technology that is able to produce metallic components of high complexity using hard to machine alloys such as Inconel 718 (IN718). Throughout the SLM process ...
Evaluation of finite element analysis on topology optimized direct metal laser sintered TI6Al4V structures
(North-West University (South Africa), 2020)
The problem under investigation in this dissertation is the validity of Finite Element Analysis (FEA) when applied to topology optimized Direct Metal Laser Sintering (DMLS) structures manufactured from Ti6AL4V with the ...
Development of a non-destructive testing method to determine the tensile fatigue life of Ti-6Al-4V additively manufactured parts
(North-West University (South Africa), 2020)
Direct metal laser sintering (DMLS) is a powder bed fusion (PBF) technology used for additive manufacturing (AM). This process deploys a laser to selectively fuse regions of a powder bed. The manufacturing of a part is ...
Investigation into microstructural and mechanical properties of a Ti-6Al-4V hybrid manufactured component
(North-West University (South Africa), 2020)
Hybrid manufacturing, as a combination of investment cast and additive manufacturing, is investigated in this study. Hybrid manufacturing acts as a potential manufacturing process for Ti6Al4V components. The project ...
Establishing a finite element model to determine the tensile strength of additively manufactured PA2200 parts
(North-West University (South Africa), 2020)
Selective laser sintering (SLS) is an additive manufacturing process that produces three-dimensional parts from computer aided design (CAD) models. This process aids in the production of parts that are singular complex and ...
Efficacy of the distortion compensation method for Selective Laser Melting specimens
(North-West University (South Africa)., 2022)
As industry 4.0 has gained momentum, the need for accurate, fast, and customizable component prototyping and fabrication has risen drastically. Additive manufacturing provides the freedom and capability to fabricate complex ...
Efficacy of Vickers indentation method to measure residual stress in additively manufactured IN718 specimens
(North-West University (South Africa)., 2022)
Selective laser melting of Inconel 718 powder (a nickel-based superalloy) is regularly used to manufacture gas turbine parts for the aerospace industry. Residual stresses that remain in components after manufacturing are ...
Development of a design cycle for an additively manufactured aircraft rudder bracket
(North-West University (South Africa)., 2021)
For traditional manufacturing processes, the variation of component quality and mechanical properties exists but these can be minimised by the implementation of process controls. Hence, it becomes key to define the full ...
Thermal fluid modelling of a titanium fluted tube condenser
(North-West University (South Africa), 2021)
Heat exchangers form a vital component in numerous energy conversion processes, ranging over multiple industries; such as mining, food, automotive and aerospace. With the continuous population growth and a drive towards ...
