RISReliability-Based Service Life Prediction of Corrosion-Affected Cast Iron Pipes Considering Multifailure Modes
Publisher: American Society of Civil Engineers
Abstract: Cast iron pipes were widely used in water distribution networks before the 196s and the majority of them have become aged and deteriorated with corrosion, which has been identified as one of the most common mechanisms of ...
Reliability-Based Service Life Prediction of Corrosion-Affected Metal Pipes with Mixed Mode Fracture
Publisher: American Society of Civil Engineers
Abstract: This paper presents a time-dependent reliability method for the assessment of corrosion-affected metal pipe failures. Two nonlinear limit state functions are proposed for brittle and ductile pipes with mixed mode fracture. ...
Efficient Solution for Calculation of Upcrossing Rate of Nonstationary Gaussian Process
Publisher: American Society of Civil Engineers
Abstract: Almost all engineering systems are not only uncertain, but also time-variant. As such, it is most appropriate to use a time-dependent reliability method, e.g., first passage probability, in the prediction of their ...
Effect of Applied Stress on Corrosion and Mechanical Properties of Mild Steel
Publisher: American Society of Civil Engineers
Abstract: There is little knowledge on the effect of stress on corrosion of mild steel and how the combination of stress and corrosion affects the mechanical properties of mild steel. This paper presents a comprehensive experiment ...
Computational Framework for Time-Dependent Reliability Assessment of Underground Water Distribution Pipeline Networks
Publisher: American Society of Civil Engineers
Abstract: AbstractThis paper proposes a comprehensive computational framework for evaluating the time-dependent
reliability of underground water distribution pipeline networks subject to corrosion-induced
deterioration. The framework ...
J-Integral Solution for Elastic Fracture Toughness for Plates with Inclined Cracks under Biaxial Loading
Publisher: American Society of Civil Engineers
Abstract: Surface cracks with different orientations have been recognized as a major cause of potential failures of thin metal structures, which are often under biaxial loading. It has been known that, for cracked ductile metals, ...
Experimental Investigation on Corrosion Effect on Mechanical Properties of Buried Cast Iron Pipes
Publisher: American Society of Civil Engineers
Abstract: A review of published literature on the corrosion of metal pipes reveals that current research on corrosion of full-size pipe sections in real soil conditions is highly limited, with almost no research reported on the ...
Factors Affecting Corrosion of Buried Cast Iron Pipes
Publisher: American Society of Civil Engineers
Abstract: Although corrosion of metal in soils has been intensively investigated in the past, a review of the published literature shows that limited research has been undertaken to understand how soil properties affect the corrosion ...
Numerical Modeling of Nonuniform Corrosion-Induced Concrete Crack Width
Publisher: American Society of Civil Engineers
Abstract: Corrosion of reinforced concrete is one of the major deterioration mechanisms that results in premature failure of the reinforced concrete structures. In practice, concrete crack width is one of the most important criteria ...
Prediction of Fracture Failure of Steel Pipes With Sharp Corrosion Pits Using Time-Dependent Reliability Method With Lognormal Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a reliability-based methodology for assessing fracture failures of steel pipes with sharp corrosion pits. Based on newly developed models of elastic fracture toughness, the simple criterion of stress ...
