Probabilistic fatigue analysis under constant amplitude loading

Journal of Constructional Steel Research, 2003
Abstract Use of a fracture mechanics-based fatigue analysis for bridge details requires that the random nature of fabrication, crack growth, fatigue-fracture failure and applied loading be properly accounted for. Prior to investigating the last item, the others may be addressed by comparing with corresponding S-N curves, which have been established ...

Fatigue of cast aluminium alloys under constant and variable-amplitude loading

International Journal of Fatigue, 1996
Abstract Three cast aluminium materials, Al 206, Al 319 and Al 390, were fatigue tested under constant- and variable-amplitude loading. A stress ratio of −1 was used for the constant-amplitude tests. The variable-amplitude load history consisted of underloads followed by constant-amplitude small cycles. The stress ratio and the number of the constant-

Fatigue Life Prediction of Composite Structures Under Constant Amplitude Loading

Journal of Composite Materials, 2007
An approach to construct the stress (or load) vs. cycles curve for composite structures under constant amplitude loading is presented. The approach is based on the assumption that the cycles to failure are a function of the probability of failure during any given cycle.

Fatigue behavior and prediction model of self-compacting concrete under constant amplitude load and incremental amplitude load

International Journal of Fatigue, 2021
Abstract To explore the fatigue fracture behavior of self-compacting concrete (SCC), constant amplitude loading tests and incremental amplitude loading tests were carried out. The experimental results of SCC were obtained and analyzed, including P-CMOD curve, fatigue life, effective crack length, fatigue crack growth (FCG) rate, stress intensity ...

Crack propagation under constant amplitude loading

Engineering Fracture Mechanics, 1985
Abstract A crack propagation law is derived on the concept that net energy released in one cycle in the vicinity of crack tip is absorbed in cyclic plastic zone incorporating the concept of crack closure. Further, the derived law is modified by introducing some more material properties, as an attempt towards generalization.

Fatigue behaviour of Polarit 725 welds under constant amplitude loading

, 1994
Fatigue testing of longitudinal non-load carrying fillet welds manufactured from both hot rolled and 21.1% cold rolled Polarit 725 stainless steel was performed. The cyclic fatigue loading was constant amplitude with R = sigmamin /sigmamax = 0. Test results show that for this material and geometry the design curves specified by SFS 2378 gave a good ...

Fatigue crack growth model for constant amplitude loading

Fatigue & Fracture of Engineering Materials & Structures, 2004
ABSTRACTA fatigue crack growth model under constant amplitude loading has been developed considering energy balance during growth of the crack. The plastic energy dissipated during growth of a crack within cyclic plastic zone and area below cyclic stress–strain curve was used in the energy balance.

Crack closure studies under constant amplitude loading

Engineering Fracture Mechanics, 1983
Abstract Crack closure experiments were performed on 6063-T6 Al-alloy using a COD-gauge for various load ranges and stress ratios. Experimental results show that for a given stress ratio, R , the crack closure load goes on decreasing as crack length increases (or K max increases) and reaches even below minimum load level at higher ...
