Ferritic/martensitic steels show very good resistance against radiation damage thus have been used in nuclear fission industry for a long time and are alterative candidates to be used in structural components of future fusion reactors. Their microstructure is complex which makes the simulation of their behaviour under extreme conditions time-consuming. However, recent developments in computational power and parallelised GPU calculations has made detailed simulation of such materials through cutting edge modelling techniques such as crystal plasticity finite element modelling possible. In this project you will be working with a team of researchers from University of Bristol to develop simulation techniques that are capable of modelling mechanical failure of ferritic martensitic materials. The project is connected to a large European project (ENTENTE) on this subject and you will be expected to interact with our European partners in particular the EDF team in France.

铁素体/马氏体钢显示出非常好的抗辐射损伤性，因此已经在核裂变工业中使用了很长时间，并且是用于未来聚变反应堆结构部件的替代候选者。它们的微观结构很复杂，这使得模拟它们在极端条件下的行为非常耗时。然而，计算能力和并行GPU计算的最新发展使得通过尖端建模技术（如晶体塑性有限元建模）对此类材料进行详细模拟成为可能。在这个项目中，您将与来自布里斯托大学的一组研究人员合作，开发能够模拟铁素体马氏体材料机械失效的模拟技术。该项目与一个大型欧洲项目（ENTENTE）有关，您将与我们的欧洲合作伙伴，特别是法国EDF团队进行互动。
