Coupling discrete dislocation dynamics with polycrystal plasticity
Lebensohn et al. [1] recently introduced an alternative description of crystal plasticity based on a fast-Fourier transform (FFT) algorithm. The FFT approach solves for the equilibrium stress and strains under the constraint of strain compatibility for systems with periodic microstructures. As currently developed, the FFT model describes plasticity with a set of elasto-viscoplastic constitutive...
متن کاملA Dislocation based Constitutive Model for Warm Forming of Aluminum Sheet
The formability of aluminum sheet can be improved considerably by increasing the temperature. At elevated temperatures, the mechanical response of the material becomes strain rate dependent. To accurately simulate warm forming of aluminum sheet, a material model is required that incorporates the temperature and strain rate dependency. In this paper, the dislocation based Alflow hardening model ...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولThe Physics of Singular Dislocation Structures in Continuum Dislocation Dynamics
Dislocations play an important role in the deformation behaviors of metals. They not only interact via long-range elastic stress, but also interact with short-range interactions; they annihilate, tangle, get stuck, and unstuck. These interaction between dislocations lead to interesting dislocation wall formation at the mesoscales. A recently developed continuum dislocation dynamics model that s...
متن کاملDetermining the regimes of cold and warm inflation in the supersymmetric hybrid model
1550-7998=20 The SUSY hybrid inflation model is found to dissipate radiation during the inflationary period. Analysis is made of parameter regimes in which these dissipative effects are significant. The scalar spectral index, its running, and the tensor-scalar ratio are computed in the entire parameter range of the model. A clear prediction for strong dissipative warm inflation is found for nS ...
