Molecular Dynamics Simulations of Crack Propagation
Crack propagation is studied in a two-dimensional binary model-quasicrystal by molecular dynamics simulations. Three regimes of motion can be discerned: An intermittent regime with stop and go, a regime of steady motion and an unstable regime with branching. In the rst two regimes the crack tip is emitting disloca-tions, which are followed by a phason wall. Along this wall the material is openi...
متن کاملMolecular dynamics simulations of crack propagation in Ni with defects
A series of molecular dynamics simulations using the embedded atom method is conducted to investigate crack propagation under mode I loading in a Ni single crystal with and without defects. The crack system (0 0 1)[1 0 0] in a slab of 160 000 atoms was studied. Defects consisting of lines of vacancies were introduced near the crack tip. Critical loads and strain energy distributions around the ...
متن کاملComparative Investigation of R213G Mutation in DNA-Binding Domain of P53 Protein via Molecular Dynamics Simulation
Introduction: P53 is a tumor suppressor protein with numerous missense mutations identified in its gene. These mutations are observed in a vast number of cancers. R213G is one of them which has a role in metastatic lung cancers. In this research, R213G was studied in comparison with the wild type via molecular dynamics simulation. Method: For the three-dimensional structure of the wild-type P53...

متن کاملObject Tracking via Dynamic Feature Selection Processes
We propose an optimized visual tracking algorithm based on the real-time selection of locally and temporally discriminative features. A novel feature selection mechanism is embedded in the Adaptive Color Names [2] (ACT) tracking system that adaptively selects the top-ranked discriminative features for tracking. The Dynamic Feature Selection Tracker (DFST) provides a significant gain in accuracy...
