چکیده انگلیسی
A newly proposed δ-mapping algorithm is extended to solve compressional elastic wave propagation in nonlinear heterogeneous media, which is characterized by spatially varying flux functions. The algorithm is coupled with the weighted essentially non-oscillatory (WENO) reconstruction so that the property of high-accuracy is preserved. Without the δ-mapping procedure, in contrast, the direct application of the WENO scheme is indicated to be deficient.
