dc.description.abstractAdditive manufacturing is a revolutionary new technology with the potential to dramatically change the way aircraft structures and components are designed and manufactured. The technology is widely becoming a popular method to manufacture new and replacement parts, and it also offers a rapid and effective repair technology for military aircraft components. The supply lead time and/or cost of replacement for aircraft components can be substantial and additive manufacturing can provide a solution to both of these problems. DST Group is currently working with University and industry partners to develop additive manufacturing based solutions for the repair and manufacture of a range of Australian military aircraft components. Currently, there are two types of repair categories used. The first is where the repair damage is such that static and fatigue strength margins remain within accepted limits so as to restore the component geometry, function and surface finish properties (i.e. non-fracture critical). The second is where the damage is more significant and the repair itself carries load and is essential to restore static and fatigue strength margins. Advanced and high-fidelity numerical modelling is an essential element required for the design, substantiation and certification of structural repairs. This presentation describes recent work to develop that advanced computational modelling capability, particularly for predicting the residual stress profile in laser cladding repairs of high strength martensitic steel materials as used in high value, critical landing gear components.en_AU
