Interface roughening and pinning
We study a simple model for the pmning of an interface by impunties with random strengths, and the depinning due to the applied pressure, m a quasi-static propagation
متن کاملRoughening and pinning of interface cracks in shear delamination of thin films
We investigate the roughening of shear cracks running along the interface between a thin film and a rigid substrate. We demonstrate that short-range correlated fluctuations of the interface strength lead to self-affine roughening of the crack front as the driving force (the applied shear stress/stress intensity factor) increases towards a critical value. We investigate the disorder-induced pert...
متن کاملInterface dynamics and kinetic roughening in fractals.
We consider the dynamics and kinetic roughening of single-valued interfaces in two-dimensional fractal media. Assuming that the local height difference distribution function of the fronts obeys Levý statistics with a well-defined power-law decay exponent, we derive analytic expressions for the local scaling exponents. We also show that the kinetic roughening of the interfaces displays anomalous...
متن کاملSpatial Competition: Roughening of an Experimental Interface
Limited dispersal distance generates spatial aggregation. Intraspecific interactions are then concentrated within clusters, and between-species interactions occur near cluster boundaries. Spread of a locally dispersing invader can become motion of an interface between the invading and resident species, and spatial competition will produce variation in the extent of invasive advance along the in...
متن کاملSpatial competition: roughening of the ecological interface
Limited dispersal distance, whether due to vegetative growth or localized 2 reproduction, generates spatial clustering. Many invasive plants, in particular, propagate clonally and aggregate spatially. Local dispersal concentrates intraspecific interactions 4 within clusters, while most between-species interactions occur near cluster boundaries. Spread of a spatially clustered, invasive plant th...
