Symposium Technical Description

The proposed symposium aims to provide an interdisciplinary forum by investigating and exploring the fundamental mechanics in manufacturing, synthesis and processing of advanced materials, structures and devices, through which, to optimize the existing techniques and to guide the development of future advanced manufacturing, synthesis and processing techniques with cost-efficiency and high-accuracy. Our plan is to have a 4-session symposium. Sessions would involve presentations from both invited speakers and submitted talks from students and faculty to present recent achievements and future tendencies. Topics that are planned to be covered may include:

  • Mechanics in manufacturing under extreme conditions (e.g. liquid environment, laser/nuclear radiation, high temperature/pressure, rapid phase transformation, constrained exploration)
  • Mechanics-guided unusual techniques of manufacturing, synthesis, processing and fabrication (e.g. self-assembly, rapid evaporation and sublimation, transfer printing, crack/buckling/delamination-driven templating, collapse of soft materials)
  • Mechanical properties and functionalities of materials, structures and devices manufactured via advanced manufacturing techniques (e.g. Additive manufacturing, self-assembly, Electrospinning, Nano-rolling/joining technologies)
  • Modeling and simulation of mechanics and materials deformation in manufacturing, synthesis and processing of advanced materials and structures

Motivation of proposed symposium:
Great achievements have been made in manufacturing technique of materials, structures and devices in the last decades from early labor-intensive casting to recent informationdigital 3D printing. Meanwhile, the ever-increasing demand for the next-generation highperformance multifunctional materials, structures and devices with small and high resolution features of relevance to such as energy, environment, healthcare and security is challenging the traditional synthesis, manufacturing and processing techniques. At the root of the manufacturing, all of the elementary steps rely on material deformation and assembly underpinned by mechanical interactions. The extended understanding and investigation of manufacturing techniques down to the nanoscale may refresh the existing techniques and also help exploring new solutions. In addition, the emerging advanced manufacturing techniques often produce materials and structures with unusual properties and functionalities which could not be described well using conventional theory and modeling. The manufacturing process – microstructure – property relations are still, to a large extent, unknown. The mechanics study in manufacturing, synthesis and processing is timely and of great interest for scientists and academics from mechanics, materials science, mechanical engineering, energy and environmental science and chemical engineering.
