Abstract

Let {Lε} be a family of elliptic systems of linear elasticity with rapidly oscillating periodic coefficients. We obtain the uniform W 1,p estimate {norm of matrix}∇;u ε{norm of matrix} p≤C{norm of matrix}f{norm of matrix} p in a Lipschitz domain Ω in Rn for solutions to the Dirichlet problem: Lε(uε)=div(f) in Ω and u ε=0 on ∂Ω, where |1p-12|<12n+δ and C, δ>0 are constants independent of ε>0. The ranges are sharp for n=2 or 3.
