In diesem Buch für Ingenieure und Studenten erfahren Sie Grundlegendes zur Finite-Elemente-Methode praxisnah anhand von überschaubaren Beispielen, die mit RFEM berechnet wurden.
Buch über FEM und RFEM
A cantilever beam with I-beam cross-section of length L is defined. The beam has five mass points with masses m acting in X-direction. The self-weight is neglected. The frequencies, the mode shapes and the equivalent loads of this 5-DOF system are analytically calculated and compared with results from RSTAB and RFEM.

Transient Response to a Constant Force
Bending of Simply Supported Triangular Plate
A simply supported equilateral triangular plate is subjected to uniformly distributed transversal load. Assuming small deformation theory and neglecting self‑weight, the maximum out‑of‑plane deflection of the plate is determined.
Clamped Elliptic Plate Under Transversal Load
An elliptic plate with clamped boundary is subjected to a uniformly distributed transversal load. Assuming small deformation theory and neglecting self‑weight, the maximum out‑of‑plane deflection of the plate is determined.
Plastic Thick-Walled Vessel
A thick-walled vessel is loaded by such an inner pressure that the vessel reaches an elastic-plastic state. While neglecting self‑weight, the analytical and numerical solutions for the radial position of the plastic zone border (under the Tresca hypothesis) are determined and compared.
