The development of new Smoothed Particle Hydrodynamics algorithm for dynamic fracture

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，包括卫星屏蔽保护、材料断裂和爆炸模拟、内部气体爆炸导致钢管破裂，所有这些都适用于制造、国防、汽车和航空航天工业。该博士项目的目标是开发、实施和基准在现实的多物理场景中模拟动态断裂的新的计算范例。招聘的博士候选人将扩展监督团队最近开发的新的平滑粒子流体动力学(SPH)算法，以包括通过黎曼求解器捕获裂纹萌生和扩展以及分叉的能力。在该算法中，粒子分裂技术易于实现。为了保证项目的影响和遗产，并在Fithty2 Technology的支持下，整个项目期间的数字发展可能会被整合到他们的SPH代码“PREONLAB”中。有趣的是，新的范例将为工业感兴趣的多材料和多阶段工程问题的统一建模奠定基础。

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.
