Abstract
We study the behavior of threshold depinning force as a function of th e shear modulus in a model of two-dimensional logarithmically interact ing vortices subject to a random potential using a simulated annealing molecular dynamics method. Peak effects and different nature of depin ning flow patterns are observed. This result suggests that peak effect is a signal of cross-over between the different pinning regimes.
