RISGraphical Assessment for Span Ranges of PSC Girder Bridges
Publisher: American Society of Civil Engineers
Abstract: Although the prestressed concrete (PSC) girder bridge is known to be more economical than other types of bridges in short and medium spans, a longer span has also been achieved by applying several strategies. This paper ...
Reference Stress Based Approach to Predict Failure Strength of Pipes With Local Wall Thinning Under Combined Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the previous work carried out by the authors, a new method to estimate failure strength of a pipe with local wall thinning subject to either internal pressure or global bending has been ...
Limit Load Solutions for Pipes With Through-Wall Crack Under Single and Combined Loading Based on Finite Element Analyses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper provides plastic limit load solutions for axial and circumferential through-wall cracked pipes based on detailed three-dimensional (3D) finite element (FE) limit analysis using ...
Failure Strength Assessment of Pipes With Local Wall Thinning Under Combined Loading Based on Finite Element Analyses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Failure assessment of a pipe with local wall thinning draws increasing attention in the nuclear power plant industry. Although many guidelines have been developed and are used for assessing the ...
Application of an Enhanced RBI Method for Petrochemical Equipments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The American Petroleum Institute guideline provides a methodology for calculating the risks of equipments installed in refineries or petrochemical plants. However, especially in connection with ...
Probabilistic Integrity Assessment of Corroded Gas Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressurized gas pipelines are subject to harmful effects from both the surrounding environments and the materials passing through them. Reliable assessment procedures, including fracture mechanics ...
Reference Stress Based Approach to Predict Failure Strength of Pipes With Local Wall Thinning Under Single Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a new method to estimate failure strength of a pipe with local wall thinning. The method is based on the equivalent stress averaged over the minimum ligament in the locally ...
On Relevant Ramberg-Osgood Fit to Engineering Nonlinear Fracture Mechanics Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper proposes a robust method for the Ramberg-Osgood (R-O) fit to accurately estimate elastic-plastic J from the engineering fracture mechanics analysis based on deformation plasticity. ...
Prediction of Failure Behavior for Nuclear Piping Using Curved Wide-Plate Test
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One important element of the Leak-Before-Break analysis of nuclear piping is how to determine relevant fracture toughness (or the J-resistance curve) for nonlinear fracture mechanics analysis. The ...
Optimum Global Failure Prediction Model of Steam Generator Tube With Two Parallel Axial Through-Wall Cracks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The 40% of wall criterion, which is generally used for the plugging of steam generator tubes, is applied only to a single crack. In the previous study (Moon et al. (2002)), a total number ...
