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，包括卫星的屏蔽保护，材料断裂和爆炸建模，遭受内部气体爆炸的破裂钢管，所有这些都适用于制造业，国防，汽车和航空航天工业。在现实的多物理场情景中建立动态断裂模型的新计算范例的实施和基准测试。招聘的博士候选人将扩展新的光滑粒子流体动力学（SPH）算法，最近开发的监督团队，包括捕捉裂纹的萌生和传播和通过黎曼解分岔的能力。在该算法中，粒子分裂技术可以很容易地实现。为了保证项目的影响和遗产，在Fifty2 Technology的支持下，整个项目期间的数值开发可能会集成到他们的SPH代码“PREONLAB”中。有趣的是，新的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。

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.
