Evaluating the Transferability of Machine-Learned Force Fields for Material Property Modeling
Shaswat Mohanty, Sanghyuk Yoo, Keonwook Kang +1
Machine-learned force fields have generated significant interest in recent years as a tool for molecular dynamics (MD) simulations, with the aim of developing accurate and efficien…
Dynamic drags acting on moving defects in discrete dispersive media: from dislocation to low-angle grain boundary
Soon Kim, Keonwook Kang, Sung Youb Kim
Although continuum theory has been widely used to describe the long-range elastic behavior of dislocations, it is limited in its ability to describe mechanical behaviors that occur…
Gravitational effect on the advancing and receding angle of a 2D Cassie-Baxter droplet on a textured surface
Donggyu Kim, Keonwook Kang, Seunghwa Ryu
Advancing and receding angles are physical quantities frequently measured to characterize the wetting properties of a rough surface. Thermodynamically, the advancing and receding a…
The effect of the misfit dislocation on the in-plane shear response of the ferrite/cementite interface
Jaemin Kim, Keonwook Kang, Seunghwa Ryu
Although the pearlitic steel is one of the most extensively studied materials, there are still questions unanswered about the interface in the lamellar structure. In particular, to…
Molecular dynamics simulation of nanoindentation on nanocomposite pearlite
Hadi Ghaffarian, Ali Karimi Taheri, Seunghwa Ryu +1
We carry out molecular dynamics simulations of nanoindentation to investigate the effect of cementite size and temperature on the deformation behavior of nanocomposite pearlite com…
Entropic Effect on the Rate of Dislocation Nucleation
Seunghwa Ryu, Keonwook Kang, Wei Cai
Dislocation nucleation is essential to our understanding of plastic deformation, ductility and mechanical strength of crystalline materials. Molecular dynamics simulation has playe…
