Abstract

This paper analyses various 2D acoustic wave propagation problems in the time domain BEM through geophysical environments. To this end the existing BEM code for the boundary nodes is expanded to optional internal nodes. Using appropriate and predominant temporal variations for the field quantities the time-related kernels are obtained explicitly. The BEM and FDM solutions presented are generated using synthetic seismograms and are seen to be stable. The qualitative agreement between the two methods is excellent.

Özet

Bu makale, jeofiziksel ortamlardan geçen çeşitli iki boyutlu akustik dalga yayılımı problemlerini zaman-domain SEM yardımıyla analiz eder. Bu, sınır noktaları için mevcut olan SEM programlarının keyfi sayıdaki iç noktalar için genişletilmesi ile başarılın Alan değişkenleri için uygun ve sıklıkla kullanılan temporal değişimlerin benimsenmesi ile zamana bağlı kernellar açık olarak elde edilir. Sunulan SEM ve SFM sonuçları sentetik sismogramların kullanılmasıyla genelleştirilir ve bu sonuçların kararlı olduğu görülür. İki metot sonuçlan arasındaki niteliksel uyum mükemmeldir.
