In diesem Buch für Ingenieure und Studenten erfahren Sie Grundlegendes zur Finite-Elemente-Methode praxisnah anhand von überschaubaren Beispielen, die mit RFEM berechnet wurden.

A simply supported beam is loaded by means of pure bending. Determine the critical load and corresponding load factor due to lateral buckling.
Member with the given boundary conditions is loaded with the moment and the axial force. Neglecting it's self-weight, determine beam's maximum torsional deformation as well as its inner torsional moment defined as a sum of a primary torsional moment and torsional moment caused by the normal force. Provide a comparison of those values while assuming or neglecting the influence of the normal force.
A thin-walled cantilever of QRO-profile is fully fixed on the left end, and the warping is enabled. The cantilever is subjected to a torque.
A beam is fully fixed (warping is restraint) on the left end and supported by the fork support (warping is enabled) on the right end. The beam is subjected to a torque, longitudinal force and transverse force.
A cantilever of I-profile is supported on the left end and it is loaded by the torque. The aim of this example is to compare the fixed support with the fork support and to investigate the behaviour of some representative quantities. The comparison with the solution by means of plates is also made.
