Abstract
Meshless methods, which have been extensively studied in last decades, are essentially improved forms of the generalized finite difference method. In this paper a generalized finite difference method for thin elastic plates and rotational shells, obtained by using Betti’s reciprocal theorem, is presented.
Özet
Son yıllarda üzerinde çok çalışılan ve düzgün bir ağ gerektirmeyen ağsız yöntemler, genelleştirilmiş sonlu fark yönteminin geliştirilmiş şekilleridir. Bu çalışmada ince elastik plaklar ve dönel kabuklara uygulanabilen, Betti teoremi kullanılarak elde edilmiş, genelleştirilmiş bir sonlu fark çözüm yöntemi sunulmaktadır.
