On the Edge Roughness of Two-Dimensional Materials
Pengjie Shi, Zhiping Xu
This study examines the roughness of mechanically cleaved edges in 2D crystals and glasses using molecular dynamics simulations with chemically accurate machine-learning force fiel…
Strength of 2D Glasses Explored by Machine-Learning Force Fields
Pengjie Shi, Zhiping Xu
The strengths of glasses are intricately linked to their atomic-level heterogeneity. Atomistic simulations are frequently used to investigate the statistical physics of this relati…
Cooperating Cracks in Two-Dimensional Crystals
Shizhe Feng, Xiaodong Zheng, Pengjie Shi +3
The pattern development of multiple cracks in extremely anisotropic solids such as bilayer or multilayer two-dimensional (2D) crystals contains rich physics, which, however, remain…
A Planning-and-Exploring Approach to Extreme-Mechanics Force Fields
Pengjie Shi, Zhiping Xu
Extreme mechanical processes such as strong lattice distortion and bond breakage during fracture are ubiquitous in nature and engineering, which often lead to catastrophic failure…
