In alpine skiing the vibrations of the skis influence the performance of a skier considerably. An alpine ski can be modelled as an Euler‐Bernoulli beam with which the vibrations of the ski can be analysed mathematically. The main characterising property of a ski is its bending stiffness, which can be measured in the lab. Since a ski is a composite material the measured bending stiffness shows variations...
Rasante Fortschritte bei der Entwicklung von Speichermedien ermöglichen die Erfassung riesiger Datenmengen. Diese liefern bei systematischer Auswertung neue Möglichkeiten zur Bestimmung von Ermüdungslasten für Eisenbahnbrücken. Während bisher die Bildung von Lastkollektiven über vorab definierte Regelzüge und eine darauf basierende Verkehrszusammensetzung die übliche Herangehensweise war, kann die...
