Experimental and numerical modelling of defects in an additively manufactured aluminium propeller

Additive manufacturing (AM) is an emerging manufacturing system in South Africa and worldwide. There is a noticeable gap, and extensive research continues on the development of non-destructive testing (NDT) defect analysis and acceptance standards for AM components in industries such as aerospace and marine. The main objectives of this research are to simulate a propeller for the prediction of component life span (Failure Analysis) and conduct a characterization of defects using industrial X-ray computed tomography for validation.
