Fracture Response of Girth-Welded Pipeline With Canoe Shape Embedded Crack Subjected to Large Plastic Deformation
(The American Society of Mechanical Engineers (ASME), 2017)Long-distance offshore pipelines always suffer large plastic deformation during installation and operation. Accompanied by high internal pressure, potential flaws are found to initiate from the girth welds, and this brings ... -
Performance-Based Reliability of ASME Piping Design Equations
(The American Society of Mechanical Engineers (ASME), 2017)In this paper, we present an exploratory study on the evaluation of reliability levels associated with the piping design equations specified by ASME Boiler and Pressure Vessel (BPV) Code, Section III. Probabilistic analyses ... -
Transient Sloshing in Partially Filled Laterally Excited Horizontal Elliptical Vessels With T-Shaped Baffles
(The American Society of Mechanical Engineers (ASME), 2017)The transient sloshing in laterally excited horizontal elliptical containers with T-shaped baffles is first investigated by using a novel semi-analytical scaled boundary finite-element method (SBFEM). The proposed method ... -
The Accounting for Geometrical Nonlinearity for Thin-Walled Pressurized Elastic Pipe With Long Axial Surface Crack
(The American Society of Mechanical Engineers (ASME), 2017)Consideration of a geometrical nonlinearity is a common practice for thin-walled pressurized structures, especially when their cross section is not a perfectly circular one due to either initial imperfections or distortions ... -
Effects of Crosshead Speed on the Quasi-Static Stress–Strain Relationship of Polyethylene Pipes
(The American Society of Mechanical Engineers (ASME), 2017)Quasi-static stress–strain relationship of polyethylene (PE) pressure pipe that plays an important role on its long-term performance has been established by removing the viscous stress component from the experimentally ... -
Numerical and Experimental Study of Elastic Interaction in Bolted Flange Joints
(The American Society of Mechanical Engineers (ASME), 2017)Bolted flange joints are widely used to connect pressure vessels and piping equipment together and facilitate their disassembly. Initial tightening of their bolts is a delicate operation because it is extremely difficult ... -
