Multiaxial fatigue of welded joints under constant and variable amplitude loadings
Fatigue & Fracture of Engineering Materials & Structures, 2001Flange‐tube joints from fine grained steel StE 460 with unmachined welds were investigated under biaxial constant and variable amplitude loading (bending and torsion) in the range of 103 to 5 × 106 cycles to crack initiation and break‐through, respectively. In order not to interfere with residual stresses they were relieved by a heat treatment.

FATIGUE DAMAGE IN 1045 STEEL UNDER CONSTANT AMPLITUDE BIAXIAL LOADING
Fatigue & Fracture of Engineering Materials & Structures, 1984The progressive nature of fatigue damage under multiaxial stress states 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 one in low cycle fatigue (LCF) region were ...

Fatigue Tests on Aluminum Specimens Subjected to Constant and Random Amplitude Loadings
Journal of Engineering Materials and Technology, 2016Increasing interest in using aluminum as the structural component of light-weight structures, mechanical devices, and ships necessitates further investigations on fatigue life of aluminum alloys. The investigation reported here focuses on characterizing the performance of cruciform-shaped weldments made of 5083 aluminum alloys in thickness of 9.53 mm ...

Stochastic Growth of Fatigue Crack under Constant Amplitude Loading
1992The scatter of experimental fatigue crack paths obtained even in very well-controlled constant amplitude loading tests is very large [Virkler et al. 1979, Ghonem & Dore 1986]. The only origin of this uncertainty is some randomness of the material properties which affect the crack propagation process.

On Three-Dimensional Fatigue Crack Propagation under Constant Amplitude Loading
Advanced Materials Research, 2010The equation of fatigue crack propagation rate is indispensable to precisely predict the fatigue life of structure containing three-dimensional crack under constant amplitude loading. Considering the crack closure effects and thickness effects in real structures, the equation of fatigue crack propagation rate under tri-axial stress state is presented ...

On Probabilistic Fatigue Crack Growth Behavior under Constant Amplitude Loads
Key Engineering Materials, 2007In this paper, an analysis of fatigue crack growth (FCG) behavior from a statistical point of view has been carried out. Fatigue crack growth tests were conducted on sixteen pre-cracked compact tension (CT) specimens of the pressure vessel (SPV50) steel in controlled identical load and environmental conditions.

Studies about the effect of stress characteristics on multi-axial high-cycle fatigue of metals are still insufficient. Up to now, little work about the effect of different ratio of stress amplitude has been done on multi-axial fatigue under the same equivalent stress.

The present paper interpreted the traditional stress-strength interference model as an equation expressing the statistical average of the probability of strength preponderating over stress. Thus, the same equation, which was traditionally applicable only in the situation of same-measure parameters, can be applied to more general situation of different ...

A statistical model for fatigue fracture under constant-amplitude cyclic loading
Engineering Fracture Mechanics, 1981Abstract A statistical approach to fatigue fracture under constant load is presented. Crack initiation due to detrimentally-acting external factors is considered, with a time-dependent rate assumed for an ensemble of growing stochastically-independent fatigue cracks.
