Summary
This paper discusses the deficiencies of boundary element stiffness matrices, gives an account of the methods proposed to circumvent these defects and proposes a new procedure to obtain symmetric stiffness matrices.
Übersicht
In diesem Aufsatz werden die Fehler diskutiert, die bei Steifigkeitsmatrizen, die mit Randelementen gewonnen wurden, auftreten, und es werden die Methoden vorgestellt, die vorgeschlagen wurden, um diese Fehler zu beheben. Ferner wird eine neue Methode vorgestellt, symmetrische Steifigkeitsmatrizen zu erhalten.
