Aligning and Chaining Carbon Nanofillers in Fibre Composites: Synergistically Improving Damage Tolerance and Diagnosis. Recent studies reveal that alternating electric or magnetic fields can rotate conductive nanofillers in polymers. This project aims to advance a new concept of aligning nano-scale reinforcements (for example, graphene nano-sheets and carbon nanofibres) along the thickness direction of composite materials. The alignment of nano-sized reinforcement will address the perennial prob ....Aligning and Chaining Carbon Nanofillers in Fibre Composites: Synergistically Improving Damage Tolerance and Diagnosis. Recent studies reveal that alternating electric or magnetic fields can rotate conductive nanofillers in polymers. This project aims to advance a new concept of aligning nano-scale reinforcements (for example, graphene nano-sheets and carbon nanofibres) along the thickness direction of composite materials. The alignment of nano-sized reinforcement will address the perennial problem of through-thickness weaknesses of fibre-reinforced composites and, at the same time, improve the electrical conductivity of composites. The synergistic improvements in the mechanical and electrical properties will improve damage tolerance and diagnosis of composites, thus expanding their applications in transport and civil construction to help reduce carbon dioxide emission.Read moreRead less
Design of Novel Metamaterials Considering Large Deformation and Plasticity. The project aims to establish an effective and efficient computational framework for the topological design of novel mechanical metamaterials considering both geometrical and material nonlinearities. This would overcome a formidable bottleneck in practical applications of metamaterials which are mostly based on linear elastic assumptions. The expected outcomes will be a new methodology and an advanced engineering design ....Design of Novel Metamaterials Considering Large Deformation and Plasticity. The project aims to establish an effective and efficient computational framework for the topological design of novel mechanical metamaterials considering both geometrical and material nonlinearities. This would overcome a formidable bottleneck in practical applications of metamaterials which are mostly based on linear elastic assumptions. The expected outcomes will be a new methodology and an advanced engineering design tool that can be used for the development of new classes of metamaterials with exceptional mechanical properties (eg negative compressibility or negative Poisson’s ratio) over a large strain range. Such novel metamaterials would have many important applications, particularly in biomedical and defence industries.Read moreRead less
Baseline-free Methods for Early Damage Diagnosis using Nonlinear Ultrasound. To address the significant limitation of existing non-destructive evaluation techniques in detecting and characterising early damage, this project aims to discover the physical nature of self-generated nonlinear waves by structural damage and to explore its potential for an entirely new class of non-destructive evaluation and structural health monitoring techniques. Major applications are expected to include a baseline- ....Baseline-free Methods for Early Damage Diagnosis using Nonlinear Ultrasound. To address the significant limitation of existing non-destructive evaluation techniques in detecting and characterising early damage, this project aims to discover the physical nature of self-generated nonlinear waves by structural damage and to explore its potential for an entirely new class of non-destructive evaluation and structural health monitoring techniques. Major applications are expected to include a baseline-free structural health monitoring technique capable of detecting and quantifying barely-visible impact damage in advanced composite materials, non-destructive evaluation of structures made by additive manufacturing, and detection of hard-to-inspect locations in unitised structures.Read moreRead less
