There is a wealth of Industrial applications which require the use of computer models for accurate prediction of dynamic fracture, including shielding protection for satellite, material fracture and explosion modelling, rupturing steel tubes subjected to internal gas explosions, all of which are applicable to the manufacturing, defence, automotive and aerospace industries.The objective of this PhD project is the development, implementation and benchmarking of a new computational paradigm for the modelling of dynamic fracture in realistic multi-physics scenarios. The recruited PhD candidate will extend the new Smoothed Particle Hydrodynamics (SPH) algorithm, recently developed by the supervisory team, to include the ability of capturing cracks initiation and propagation and bifurcation through Riemann solvers. In this algorithm, particle splitting technique can be easily implemented. To guarantee the impact and the legacy of the project, and with the support of Fifty2 Technology, the numerical developments throughout the project duration will potentially be integrated into their SPH code "PREONLAB". Interestingly, the new paradigm will pave the foundation for the unified modelling of multi-material and multi-phase engineering problems of interest to industry.

有大量的工业应用需要使用计算机模型来准确预测动态断裂，包括卫星的屏蔽保护、材料断裂和爆炸建模、内部气体爆炸下的钢管破裂，所有这些都适用于制造、国防、汽车和航空航天工业。这个博士项目的目标是开发、实施和基准测试一种新的计算范式，用于现实多物理场场景中的动态断裂建模。所招募的博士生将扩展监督团队最近开发的新平滑粒子流体动力学（SPH）算法，包括通过黎曼求解器捕获裂纹萌生、传播和分叉的能力。在该算法中，粒子分裂技术可以很容易地实现。为了保证该项目的影响力和遗产，并在 Fifty2 Technology 的支持下，整个项目期间的数值发展将有可能被整合到其 SPH 代码“PREONLAB”中。有趣的是，新范式将为工业界感兴趣的多材料和多相工程问题的统一建模奠定基础。
