RISInvestigation of Fatigue Crack Propagation in Line Pipes Containing an Angled Surface Flaw
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The angled crack problem has been given special attention in the recent years by fracture mechanics investigators due to its close proximity to realistic conditions in engineering structures. ...
A Mesoscale Model of Plasticity: Dislocation Dynamics and Patterning (One Dimensional)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, we developed a physically based mesoscale model for dislocation dynamics systems to predict the deformation and spontaneous formation of spatiotemporal dislocation patterns over microscopic space and time. ...
Applicability of Equivalent Constant Amplitude Loading for Assessing the Fatigue Life of Pipelines and Risers and the Influence of Compressive Stress Cycles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue life assessment of pipelines and risers is a complex process, involving various uncertainties. The selection of an appropriate fatigue model is important for establishing the inspection intervals and maintenance ...
A Comprehensive Parametric Finite Element Study on the Development of Strain Concentration in Concrete Coated Offshore Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The strain concentration at the field joint (FJ) of the commonly used concrete coated offshore pipelines is considered and discussed in this paper. The details of a 3D finite element (FE) ...
Effect of Lüders Plateau on Fracture Response and Toughness of Pipelines Subject to Extreme Plastic Bending
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The reeling technique presents an economical pipeline installation method for offshore oil and gas applications, especially for thick-wall (low D/t) pipelines. During reeling, the pipe is subjected ...
On the Effectiveness of Composites for Repair of Pipelines Under Various Combined Loading Conditions: A Computational Approach Using the Cohesive Zone Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: ASTM PCC-2 standard provides a series of equations for establishing the composite repair's thickness required for bringing the capacity of dented/damaged pipes, to their original design state. However, the accuracy of the ...
Multiscalar Mechanisms of Shrinking Small-Size Cities: The Case of Kermanshah Province
Publisher: ASCE
Abstract: Despite scattered attempts to frame the processes of population and economic decline in cities of the global South through urban shrinkage, mechanisms identified in the core studies of this concept do not easily translate ...
Correction to Parshall Flume Calibrations at Low Discharges
Publisher: American Society of Civil Engineers
Abstract: An inspection of the original study that developed the rating equations for Parshall flumes indicates that the calibration tests were not conducted for as low of flows as currently recommended for their use. An experimental ...
Seismic Hazard Assessment of the Tehran Region
Publisher: American Society of Civil Engineers
Abstract: The region around Tehran is considered a high seismicity area. It should arouse more concern to the seismic safety of this city given that the last damaging earthquake occurred nearly 200 years ago, and the geotechnical ...
Decisions of Landlords about Their Renters and Rental Units after Disasters
Publisher: ASCE
Abstract: Postdisaster recovery in the rental housing submarket has attracted scant attention in both policy and scholarly circles. In particular, little is known about landlords’ decisions on whether to keep their previous renters, ...
