Analytical and Experimental Investigation of Low-Cycle Fatigue Fracture in Structural Steel
… cyclic deformations is commonly described as Low-Cycle Fatigue (LCF). Fracture in steel structures caused by earthquakes can be associated with this mechanism. Mathematical expressions describing the material deterioration due to LCF are often referred to as LCF laws. The accurate …

Fatigue Damage and Small Crack Growth During Biaxial Loading
The progressive nature of fatigue damage under biaxial loading has been investigated. Experiments were performed on thin-wall tubular specimens of 1045 steel in tension, torsion, and combined tension-torsion loading. Two equivalent strain amplitudes, one in the high cycle fatigue (HCF) region and …
