Wavefield forward modeling with the pseudo - spectral method in viscoelastic and azimuthally anisotropic media 各向異性黏彈性介質(zhì)偽譜法波場模擬
Then , the numerical simulation has been made by pseudo - spectral method ( psm ) , and the waterfall plot of the wave was draw with matlab . so the effects of different variational walls on the nonlinear surface waves could be analyzed 然后利用擬譜方法進行數(shù)值模擬,用matlab軟件繪制出非線性表面波的瀑布圖,由此研究壁面變化對非線性表面波的影響。
In this paper , a new heterogeneous anisotropic constitutive model of fractured media was presented , and the properties of elastic waves excited from a two - dimensional ( 2d ) point source propagation in 2d fractured rocks were investigated by the pseudo - spectral method ( psm ) 本文提出了一種新的非均勻各向異性隨機裂縫介質(zhì)本構(gòu)模型,用偽譜法模擬了二維點源產(chǎn)生的彈性波在二維復雜巖石中的傳播。
