Dislocation jamming and Andrade creep
M. -Carmen Miguel, Alessandro Vespignani, Michael Zaiser +1
We simulate the glide motion of an assembly of interacting dislocations under the action of an external shear stress and show that the associated plastic creep relaxation follows A…

Depinning of a dislocation: the influence of long-range interactions
Stefano Zapperi, Michael Zaiser
The theory of the depinning transition of elastic manifolds in random media provides a framework for the statistical dynamics of dislocation systems at yield. We consider the case…
