Numerical Simulation of New Cementitious Composite Materials

本项目将重点研究一种新型胶结建筑材料体系（或简称新材料）的数值模拟。在项目中开发的数值工具将增强对新材料的理解，用于指导未来材料的开发，并最终用于设计由新材料形成的结构。即将开发的有限元模型将利用卡迪夫监工开发的一种新的微机械材料愈合理论。开发的模型将在商业有限元程序lusas中实施。这种新型复合材料包括一个胶凝基质，其中嵌入了局部增强的微型血管单元。这种材料系统的行为是复杂的，包括微观开裂、宏观开裂、愈合和裂纹桥接。该项目与以下EPSRC研究领域相关：生长：连续力学，维护：工程设计，基础设施和城市系统，材料工程-复合材料，数值分析和结构工程在卡迪夫，案例学生将加入M4L小组的博士后和博士研究人员组成的动态团队，研究自愈材料的不同方面。重要的是，她/他将与实验学家以及其他数值研究人员一起工作。M4L集团目前正在领导EPSRC项目拨款，是欧洲培训网络的一部分。这意味着M4L与其他国家的研究小组有着密切的联系，并为学生提供了与海外顶尖大学的研究人员互动的绝佳机会。个案学生将受益于卡迪夫大学为博士生提供的广泛课程，这些课程有助于培养研究、技术和专业技能。

The project will focus on the numerical simulation of a new cementitious construction material system (or new material for short). The numerical tools to be developed in the project will enhance the understanding of the new material, be used to guide future material developments and ultimately be employed in designing structures formed from the new material. The finite element models to be developed will make use of a new micro-mechanical material-healing theory developed by the Cardiff supervisors. The models developed will be implemented in the commercial finite element program LUSASThe new composite material comprises a cementitious matrix with embedded -locally reinforced- mini-vascular units. The behaviour of this material system is complex and encompasses micro-cracking, macro-cracking, healing and crack bridging. The project is relevant to the following EPSRC Research areas:Grow: Continuum Mechanics , Maintain: Engineering Design, Infrastructure and Urban Systems, Materials Engineering-Composites, Numerical Analysis and structural Engineering In Cardiff, the case-student will join a dynamic team of Post-Doc and PhD researchers in the M4L Group investigating different aspects of self-healing materials. Importantly, she/he will work with experimentalists as well as other numerical researchers. The M4L Group is currently leading an EPSRC Programme grant and is part of a European training network. This means that M4L has strong links with research groups in other countries and provides a great opportunity for the student to interact with researchers at leading overseas universities. The case-student will benefit from an extensive range of courses available to PhD students in Cardiff that help develop research, technical and professional skills.
