Research Areas

Dr. Yuantong Gu and his research team have defined two main research areas:

• Advanced Numerical Modelling and Simulation for Methods for advanced material and mechanical engineering
• Nanotechnology

 

Advanced Numerical Modelling and Simulation for Advanced Material and Mechanical Engineering

Due to the new developments in material and mechanical engineering, numerical modelling and simulation are becoming more and more important. The existing modellings are insufficient for many modern engineering problems including moving boundary problems, strong nonlinear problems, multi-fields problems, and multiple scale problems. A group of new numerical modelling and simulation techniques are being developed and applied to practical engineering problems. The wide acceptance of these methods both in research and industry has led to the research in the area of development of advanced numerical modelling tools for engineering.

Dr. Yuantong Gu’s research in this area is focused on:

• Advanced numerical modelling and simulation for mechanical engineering applications;
• Multiscale modelling and simulation for material and mechanical engineering;
• Advanced/Modified Finite Element Method for engineering applications;
• Novel Meshless (Meshfree) techniques and its’ applications

 

Nanotechnology

Nanotechnology has emerged as the technology for the future. The possible applications of this technology are immense and relate to almost all areas: energy, environment, telecommunication, healthcare etc.

As the industrial conquest of nanotechnology has started, Dr. Yuantong Gu and his research team have started to investigate the fundamental part of nano technology to understand its behaviour. The teams' research is focused on : developing advanced multiscale modelling techniques crossing macro-, micro- and nano- dimensions for nano-manufacturing and nano-materials fabrication. The aim is to break through what has become an impasse in these fields by developing an innovative multiscale technique to allow reliable analysis across nanoscopic to macroscopic dimensions. The advance will enable us to precisely explore the deformation mechanisms in complex systems of nano-manufacturing and nano-materials, so that quality and effectivity of these systems will be significantly improved through controlling and designing the whole processing in not only the macro/micro-scale but also the nano-scale.

Dr. Yuantong Gu’s research in this areas focuses on:

• Advanced multiscale modelling techniques crossing macro-, micro- and nano- dimensions for nano-manufacturing and nano-materials fabrication;
• Coupled Molecular Dynamics/ Monte Carlo/Meshless modelling technique;
• Numerical investigation for the crossing-scale deformation mechanism in material;
• Multiscale characterization techniques for material and manufacturing.
