Ingenieur-Archiv Aims and scope Submit manuscript

Summary

The governing equations for thin-walled members subjected to axial force, biaxial bending and torsion are formulated by variational method. The resulting equations differ slightly with currently accepted governing equations. Numerical examples are solved for simple problems to illustrate some of the features of the proposed equations.

Übersicht

Die beschreibenden Differentialgleichungen für dünnwandige Bauglieder, die durch achsiale Kräfte, biachsiale Biegung und Torsion beansprucht sind, werden nach einem Variationsverfahren aufgestellt. Die so erhaltenen Gleichungen unterscheiden sich etwas von den zur Zeit üblichen Gleichungen. Um die Eigenschaften der jetzt vorgeschlagenen Gleichungen zu zeigen, werden numerische Ergebnisse für einige einfache Aufgaben angegeben.
