Einfluss der Prüffrequenz auf Dauerfestigkeits- und Rissausbreitungsverhalten verschiedener Stähle

RFCS project „FREQTIGUE“

Motivation

Higher ranges of cycling frequencies reduce testing time for fatigue tests of engineering steels

Objectives

Validation of fatigue testing procedures, guidelines and recommendations for suitable testing practises as a function of the frequency for time reduction and reliable data

Methods

• Fatigue tests including strength and crack growth rate with different levels of cycling frequency in cooperation with several european partners
• Cyclic uniaxial, torsion, 3-point-bending and component tests with different R ratios
