Abstract

This paper deals with the evolution of fronts or interfaces propagating with normal velocity v_n=f−cκ where f is a spatially periodic function, c a constant and κ the mean curvature. This study is motivated by the propagation of phase boundaries and dislocation loops through heterogeneous media. We establish a homogenization result when the scale of oscillation of f is small compared to the macroscopic dimensions, and show that the overall front is governed by a geometric law v_n=f(n). We illustrate the results using examples. We also provide an explicit characterization of f in the limit c → ∞.
