Adaptive Reliability-Based Inspection Strategies for Structures Subject to Fatigue
Metallic structures subject to substantial load-induced fatigue must be inspected from time to time and, possibly, repaired or even put out of service if the damage has reached critical...
Objective Comparison of Fatigue Crack Growth Laws
This paper presents objective criteria for choosing between different fatigue crack growth laws to represent a material's fatigue behavior based on a data set containing multiple...
Fatigue Crack Closure Under Random Loading
The goals of the research are to determine fatigue crack growth rates for stationary random amplitude loadings with arbitrary mean stress. Fatigue crack closure theory is applied to justify...
Fatigue Reliability of Prestressed Concrete Bridges
Experimental studies indicate that fatigue is a random phenomenon. Therefore, the approach is based on probabilistic methods. The fatigue life of the prestressed concrete girder is estimated...
Effect of the Uncertainty About the Fatigue Limit on Highway Bridge Reliability
Current fatigue design specifications for welded steel highway bridges subjected to high traffic volumes require the design to be capable of resisting high-cycle, long life conditions...
Reliability Assessment of Pressurized Fuselages with Multiple-Site Fatigue Cracks
Multiple-site damage could cause a catastrophic structural failure of aged aircraft. A reliability analysis is proposed for an assessment of the capability of visual inspection on multiple-site...
Mt. Elbert Pumped Storage Trashrack Failure
The failure of three trashrack sections for unit 2 at the suction-draft tube intake occured after one year in service. However, the trashracks for unit 1 had five years of service with...
Damage Prediction in Laminated Composites with Continuum Damage Mechanics
A finite element model is developed for laminated composite plates experiencing fatigue load induced microstructural damage. Continuum damage mechanics based constitutive relationships,...
Laboratory Fatigue Investigation of a GRP Bridge
A fatigue study of a 4.9 m glass-reinforced plastic bridge indicated a resistance to 1.6 million cycles of load without extensive damage to joints or elements. Viscoelastic creep occurred...
Uni- and Bi-Axial Compressive Fatigue of Fiber Concrete
Fatigue behavior of fiber reinforced concrete is studied under uniaxial and biaxial loadings. The S-N curves and the cyclic deformations of fiber concrete are compared to those of plain...
Fatigue and Fracture Evaluation of Riveted Bridge Members
Among the major concerns of bridge engineers today are the fatigue damages that have been accumulated in riveted members and the safety of riveted structures. Many of these structures...
Fatigue Strength of Corroded Rolled Beams
Highway and railway bridges fabricated from ASTM A7, A36, and A572 steels will corrode if the paint system is allowed to fail for lack of maintenance. Corroding members lose cross section...
