摘 要: In this talk, we discuss the multiscale asymptotic approach for the ablative materials with a periodic microstructure. The system satisfies a nonlinear parabolic equation with rapidly oscillating discontinuous coefficients. To save the computational cost, we present the homogenization method and first/second multiscale asymptotic. An explicit rate of convergence is derived for the first/second order multiscale asymptotic. Several numerical tests are carried out to confirm the efficiency and accuracy of the approaches.
