Summary:

Low-dimensional nanoscale materials including 2D materials (such as graphene, hexagonal boron nitride, silicene, stanene, germanene, transition metal-dichalcogenides) and 1D materials (such as nanotubes and nanowires) exhibit extraordinary material properties. They show outstanding potential for a number of critical application areas including nanoelectronics, energy, defense, aerospace, biotechnology, and nanocomposites. In spite of decades-long developments in the field of fracture mechanics, it remains a challenge to describe and predict the condition for crack nucleation and propagation in low-dimensional materials, due to intricate correlations between surface structure, topological defects, porosity, and heterogeneity at multiple scales. This symposium invites researchers and experts in the field to discuss recent developments and state-of-the-art practices used to investigate and understand the criteria for crack nucleation and propagation in 1D and 2D materials. There will be four sessions in this symposium. The first session will focus on crack nucleation in 1D materials; the second session will focus on crack propagation in 1D materials; the third session will focus on crack nucleation in 2D materials; and the fourth session will focus on crack propagation in 2D materials. The talks are expected to cover theoretical, computational, and experimental research on fracture in nanoscale materials.
