Symposium S-Mechanical Behavior at the Nanoscale

The mechanics of materials in small volumes provides the basis for better understanding of macroscale mechanics including multi-scale phenomena such as fracture and behavior at interfaces. It is also essential to the development of new nanotechnologies based on low dimension objects such as particles, wires, tubes, sheets and films. Imposed spatial confinement can controllably probe length scales governing cooperative defect behavior in crystals, glasses, and hierarchal materials, while proximity of interfaces or free surfaces can alter thermomechanical relaxation and equilibrium.

This symposium focuses on the mechanical properties of small-volume and low-dimensional materials. These range from nanowires and nanotubes to microscale or nanoscale materials. The symposium invites abstracts that discuss sample size effects, nanoscale mechanical testing, in-situ characterization and modeling of small-scale materials. The properties to be covered include elasticity, strength, plastic flow, fatigue and fracture. Special focus sessions on emerging topics in 2D material mechanics, soft matter deformation and mechanical nanofabrication and forming are planned. Abstracts that address modeling aspects are also solicited, with emphasis on unusual mechanisms that influence the plasticity of small-volume materials.

Topics will include:

  • Mechanics of 2D materials such as graphene, hexagonal boron nitride, etc.
  • Small volume crystal plasticity: Size effects in indention, pillar compression, thin films, wires and tubes, particles, grains, twin domains
  • Ex-situ and in-situ (SEM, TEM, XRD, neutron, etc.) mechanical characterization methods
  • Fracture mechanics at small scales: Experiments and simulations at atomic scale, temperature effects, strain-rate effects, microstructure effects
  • Multiscale modeling and simulations of mechanical behavior of nanostructured materials; Theory of deformation behavior and mechanisms.
  • Confinement effects in glasses and soft matter: Metallic glasses, polymers, hierarchical materials, biomaterials such as collagen, chitin, and keratin
  • Role of small-scale deformation mechanics in nanomanufacturing: Mechanical nanofabrication and forming, EUV resist collapse, nanoimprint
