Additive Manufacturing (AM) is a new manufacturing process that 'grows' 3D parts, layer by layer. By allowing the construction of extremely complex geometries, it has led to exciting innovations in the manufacturing industry. It is clear that, as a result of its ability to generate components that are structurally, thermally and/or flow optimised; AM has the potential to be applied in many areas of the aerospace industry. Before this can happen, however, it has to be established that the developed technology will significantly reduce the risk of component failure. To that end, the aim of this project is to establish how the inclusion of components that have been created using AM will reduce the probability of failure of aerospace structures. This will be based around a computational modelling approach and will make use of advanced Finite Element software as well as a technique known as Subset Simulation, which can be used to efficiently estimate failure probabilities. This work will be followed up by a cost benefit analysis, which will establish the merits of adopting AM in the aerospace industry. As well as working within the area of Aerospace Engineering, the successful applicant will also work closely with colleagues from the Department of Computer Science. This is to ensure the efficient running of the large computational models that will be involved in the project. Moreover, the student will also work closely with the Renishaw Additive Manufacturing group. The project therefore provides a unique opportunity to work with a world leading engineering and scientific technology company which has an excellent track record in research

增材制造（AM）是一种新的制造工艺，可以一层一层地“生长”3D零件。通过允许构造极其复杂的几何形状，它在制造业中带来了令人兴奋的创新。很明显，由于其能够生成结构，热和/或流动优化的组件；增材制造在航空航天工业的许多领域都有应用的潜力。然而，在这种情况发生之前，必须确定所开发的技术将显著降低组件故障的风险。为此，该项目的目的是确定如何包含使用增材制造的组件将降低航空航天结构失效的可能性。这将基于计算建模方法，并将利用先进的有限元软件以及一种称为子集模拟的技术，该技术可用于有效地估计故障概率。这项工作之后将进行成本效益分析，这将确定在航空航天工业中采用增材制造的优点。除了在航空航天工程领域工作外，成功的申请人还将与计算机科学系的同事密切合作。这是为了确保项目中涉及的大型计算模型的有效运行。此外，学生还将与雷尼绍增材制造团队密切合作。因此，该项目提供了与世界领先的工程和科学技术公司合作的独特机会，该公司在研究方面拥有出色的记录
