  journal={SIAM J. Math. Analysis},
We consider the evolution by mean curvature in a highly heterogeneous medium, modeled by a periodic forcing term, with large L∞-norm but with zero average. We prove existence of a homogenization limit, when the dimension of the periodicity cell tends to zero, and show some properties of the effective velocity. Key-words : Homogenization, propagation of fronts, heterogeneous media, evolution by mean curvature, viscosity solutions AMS subject classifications : 35B27, 35K55, 35J20, 53C44, 49L25
