Kerbbeanspruchungen bei synchronen nichtproportionalen Belastungskombinationen zweier schwingender Lastkomponenten mit Nennmittelspannungsunterschied und betriebsaehnlich schwingenden Belastungen

Abstract

The present paper completely analyzes and investigates the general case of multi-axial synchronous nonproportional composite load combinations and determines the laws governing the complete load history at the point of maximum stress (critical node in the notched element) under this type of loading. Systematic detailed investigations were conducted for two load components, normal force and torsion, both oscillating, each with varying nominal mean stresses and amplitudes. In conclusion, the influence of an extension of the load situation to quasi-operational loads in each case and, thus, the most general synchronous nonproportional load combination was investigated.
