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 …

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 …

Low cycle fatigue life improvements realized by reduced thermal strain due to flange separation in bolted joints
Low cycle fatigue (LCF) life is an essential aspect in aircraft engine component design, particularly concerning structural members. Realistic finite element modeling is critical in obtaining life predictions that accurately represent fielded parts. One of the most challenging designs to model …

High temperature creep-fatigue behavior of alloy 617 and alloy 230
… used in the VHTR is predicted to be creep-fatigue damage, which arises due to startup and shutdown or power transients during normal operation. The mechanism of synergic interaction between creep and fatigue is not well understood and there are no effective modeling methods for predicting …
