dc.description.abstract | We develop a semi-discrete particle method for Volterra dislocation currents in which the particles, or
monopoles, represent an element of line and carry a Burgers vector. The monopoles move according to
mobility kinetics driven by elastic and applied forces. The divergence constraint of Volterra dislocation
currents is enforced weakly through mesh-free interpolation and an explicit linear connectivity, or
‘sequence’, between the monopoles need not be defined. In this sense, the method is ‘line-free’,
i. e., it sidesteps the need to track dislocation lines. This attribute offers significant computational
advantages in terms of simplicity, robustness and efficiency, especially as regards the tracking of
complex dislocation patterns, including topological transitions. We illustrate the range and scope of
the method, by means of an example of application concerned with the plastic hardening of nano-sized
grains under monotonic loading | es |
