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裂缝，包括屏蔽卫星的保护，物质裂缝和爆炸建模，遭受内部气体爆炸的破裂钢管，所有这些管都适用于制造业国防，汽车和航空航天行业。该博士学位项目的目的是开发，实施和基准测试新的计算范式，用于在现实的多物理场景中进行动态裂缝建模。招募的PhD候选人将扩展由监督团队最近开发的新的平滑粒子流体动力学（SPH）算法，以包括捕获通过Riemann solvers捕获裂纹启动和传播以及分叉的能力。在此算法中，可以轻松实现粒子分裂技术。为了确保项目的影响和遗产，并在Fifty2技术的支持下，整个项目持续时间的数值发展可能会集成到其SPH代码“ PreonLab”中。有趣的是，新的范式将为工业兴趣的多材料和多相工程问题的统一建模奠定基础。
