:We study the Cauchy problem for systems of 3-D quasilinear wave equations satisfying the null condition with low regularity initial data. In the radially symmetric case, we prove the global existence for every small data in $H^3 \times H^2$ with a low weight and apply the result to 3-D nonlinear elastic waves.
