On the motion of curved dislocations in three dimensions: Simplified linearized elasticity
Irene Fonseca, Janusz Ginster, Stephan Wojtowytsch
It is shown that in core-radius cutoff regularized simplified elasticity (where the elastic energy depends quadratically on the full displacement gradient rather than its symmetriz…

Strain-Gradient Plasticity as the -Limit of a Nonlinear Dislocation Energy with Mixed Growth
Janusz Ginster
In this paper a we derive by means of -convergence a macroscopic strain-gradient plasticity from a semi-discrete model for dislocations in an infinite cylindrical crystal. In co…

A Functional and its Relaxation for Joint Motion Estimation and Image Sequence Recovery
Sergio Conti, Janusz Ginster, Martin Rumpf
The estimation of motion in an image sequence is a fundamental task in image processing. Frequently, the image sequence is corrupted by noise and one simultaneously asks for the un…
