Fracture of Notched Single Crystal Silicon
Nicholas P. Bailey, James P. Sethna
We study atomistically the fracture of single crystal silicon at atomically sharp notches with opening angles of 0 degrees (a crack), 70.53 degrees, 90 degrees and 125.3 degrees. S…
KMC-MD Investigations of Hyperthermal Copper Deposition on Cu(111)
J. M. Pomeroy, J. Jacobsen, C. C. Hill +2
Detailed KMC-MD (kinetic Monte Carlo-molecular dynamics) simulations of hyperthermal energy (10-100 eV) copper homoepitaxy have revealed a re-entrant layer-by-layer growth mode at…
Crack Growth Laws from Symmetry
James P. Sethna
Reviewing work done in collaboration with Jennifer Hodgdon, we derive the most general crack growth law allowed by symmetry for mixed-mode three-dimensional fracture. We do so usin…
Formal Considerations about Fracture: Nucleation and Growth
James P. Sethna
In this paper, we'll answer several abstract, formal questions about the nature of crack growth and nucleation. Bringing a field theory point of view to fracture illuminates things…
Dislocation Mobility in Two-dimensional Lennard-Jones Material
N. Bailey, J. Sethna, C. Myers
In seeking to understand at a microscopic level the response of dislocations to stress we have undertaken to study as completely as possible the simplest case: a single dislocation…
