Discrete dislocation dynamics simulations of twin size-effects in magnesium
A dislocation1012 twin boundary (TB) interaction model was proposed and introduced into discrete dislocation dynamics simulations to study the mechanical behavior of micro-twinned Mg. Strong strain hardening was captured by current simulations, which is associated with the strong TB’s barrier effect. In addition, twin size effects with small TB spacing leading to a strong yield stress, were obs...
متن کاملA parallel algorithm for 3D dislocation dynamics
Dislocation dynamics (DD), a discrete dynamic simulation method in which dislocations are the fundamental entities, is a powerful tool for investigation of plasticity, deformation and fracture of materials at the micron length scale. However, severe computational difficulties arising from complex, long-range interactions between these curvilinear line defects limit the application of DD in the ...
متن کاملModelling plastic deformation in a single-crystal nickel-based superalloy using discrete dislocation dynamics
Background: Nickel-based superalloys are usually exposed to high static or cyclic loads in non-ambient environment, so a reliable prediction of their mechanical properties, especially plastic deformation, at elevated temperature is essential for improved damage-tolerance assessment of components. Methods: In this paper, plastic deformation in a single-crystal nickel-based superalloy CMSX4 at el...
متن کاملDiscrete dislocation dynamics simulations to interpret plasticity size and surface effects in freestanding FCC thin films
Strong size effects have been experimentally observed when microstructural features approach the geometric dimensions of the sample. In this work experimental investigations and discrete dislocation analyses of plastic deformation in metallic thin films have been performed. Columnar grains representative of the film microstructure are here considered. Simulations are based on the assumptions th...
متن کاملAn efficient hybrid 2D/3D thin film discrete dislocation dynamics
Crystalline thin fi lms are increasingly used in semiconductor devices, ferroelectric and ferromagnetic devices, biomedical components, fuel cells, solar cells, and wear-resistant coatings. Given their widespread use, understanding the unique mechanisms that control their properties is critical. This has proven challenging because the properties of thin fi lms do not obey bulk scaling laws. In ...
