Impulsive Motion in a Cylindrical Fluid-Filled Tube Terminated by a Converging Section
(The American Society of Mechanical Engineers (ASME), 2019)The syringe in a subcutaneous auto-injector may be subjected to internal pressure transients due to the normal operation of the injection mechanism. These transients are similar to transients in fluid-filled pipelines ... -
Evaluation Method for Seismic Fatigue Damage of Plant Pipeline
(The American Society of Mechanical Engineers (ASME), 2019)Although acceleration and cumulative absolute velocity (CAV) are used as seismic indexes, their relationship with the damage mechanism is not yet understood. In this paper, a simplified evaluation method for seismic fatigue ... -
Study on the Failure Mechanism of Burn-Through During In-Service Welding on Gas Pipelines
(The American Society of Mechanical Engineers (ASME), 2019)We conclude on the governing mechanism of burn-through and identify the area of highest risk for burn-through occurrence due to a specific combination of loading in this area. In order to investigate the mechanism of ... -
Numerical Analysis of Mechanical Behavior of Buried Pipes in Subsidence Area Caused by Underground Mining
(The American Society of Mechanical Engineers (ASME), 2019)The buried pipe crossing the subsidence area is prone to failure. The mechanical behavior of buried pipe in subsidence area was investigated in this paper. Effects of subsidence displacement, pipe parameters and soil ... -
A Framework for Risk-Based Integrity Assessment of Unpiggable Pipelines Subject to Internal Corrosion
(The American Society of Mechanical Engineers (ASME), 2019)Many pipelines are unpiggable, which means they cannot be examined by in-line inspections (ILI). Existing industry practice for integrity assessment of unpiggable pipelines is not risk based, which precludes optimal ... -
Finite Element Method Simulations to Study Factors Affecting Buried Pipeline Subjected to Debris Flow
(The American Society of Mechanical Engineers (ASME), 2019)As the debris flow caused by sustained rainfall would cause destructive damage to buried pipeline, the safety of buried pipeline under impact of debris flow draws increasing attention. This paper focuses on the mechanical ... -
Variation of Beremin Model Parameters With Temperature by Monte Carlo Simulation
(The American Society of Mechanical Engineers (ASME), 2019)In this work, variation of the Beremin parameters with temperature for reactor pressure vessel material 20MnMoNi55 steel is studied. Beremin model is used, including the effect of plastic strain as originally formulated ... -
A New Nonproportional Low Cycle Fatigue Life Prediction Method for Type 304 Stainless Steel
(The American Society of Mechanical Engineers (ASME), 2019)A new method is put forward to predict fatigue life for low cycle nonproportional loading based on the Itoh criterion. The proposed method considers the multi-axiality influence on the reference maximum principal strain ... -
Investigation on Redesigning Strategies for Water-Hammer Control in Pressurized-Piping Systems
(The American Society of Mechanical Engineers (ASME), 2019)This paper explored and compared the effectiveness of the inline and the branching redesign strategies used to control water-hammer surges initiated into existing steel piping systems. The piping system is handled, at its ... -
A Simplified Dispersion Compensation Algorithm for the Interpretation of Guided Wave Signals
(The American Society of Mechanical Engineers (ASME), 2019)Due to the multimodal and dispersive characteristics of guided waves, guided wave testing signals are always overlapped and difficult to separate for correct interpretations. To this end, a simplified dispersion compensation ... -
Plastic Collapse Stresses for Pipes With Inner and Outer Circumferential Cracks
(The American Society of Mechanical Engineers (ASME), 2019)Bending stresses at incipient plastic collapse for pipes with circumferential surface cracks are predicted by net-section stress approach. Appendix C-5320 of ASME B&PV Code Section XI provides an equation of bending ... -
