Core energy and regularization parameters of non-singular continuum theories of dislocations using atomistic simulations
Kamyar M Davoudi
The dislocation core is an important region as it controls many important properties of materials. Elasticity breaks down in the core and the stress, force, and energy diverge at t…
Temperature Dependence of the Yield Strength of Aluminum Thin Films: Multiscale Modeling Approach
Kamyar Davoudi
Modeling deformation at elevated temperatures using discrete dislocation dynamics (DDD) is a recent area of high interest. However, the literature dedicated to this subject fails t…
Dislocation evolution during plastic deformation: Equations vs. discrete dislocation dynamics study
Kamyar M. Davoudi, Joost J. Vlassak
Equations for dislocation evolution bridge the gap between dislocation properties and continuum descriptions of plastic behavior of crystalline materials. Computer simulations can…
Bauschinger Effect in Thin Metal Films: Discrete Dislocation Dynamics Study
Kamyar M. Davoudi, Lucia Nicola, Joost J. Vlassak
The effects of dislocation climb on plastic deformation during loading and unloading are studied using a two-dimensional discrete dislocation dynamics model. Simulations are perfor…
Nanomechanics of a screw dislocation in a functionally graded material using the theory of gradient elasticity
Kamyar Davoudi, Hossein Davoudi, Elias Aifantis
The modest aim of this short article is to provide some new results for a screw dislocation in a functionally graded material within the theory of gradient elasticity. These result…
