RISA New Holistic Approach for Subsea Pipeline Upheaval Buckling Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For a trenched and buried pipeline, the propensity to upheaval buckling (UHB) is a major design concern. Predictive UHB design is typically required at the outset to determine both trenching and backfilling requirements. ...
Subsea Pipeline Lateral Buckling Design—Strain Concentration or Strain Capacity Reduction Factors
Publisher: The American Society of Mechanical Engineers (ASME)
Fatigue Design and Analysis of Offshore Pipelines and Risers Subjected to Waves and Currents
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The industry consensus would appear that the effect of currents on wave-induced fatigue damage accumulation is assumed as insignificant and can be ignored. Only when dealing with stability, ultimate limit state design, and ...
Modeling and Analysis of Nonlinear Wave Propagation in One-Dimensional Phononic Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Different from elastic waves in linear periodic structures, those in phononic crystals (PCs) with nonlinear properties can exhibit more interesting phenomena. Linear dispersion relations cannot accurately predict band-gap ...
Controlling Out-of-Plane Elastic Shear Wave Propagation With Broadband Cloaking
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A major challenge in designing a perfect invisibility cloak for elastic waves is that the mass density and elasticity tensor need to be independent functions of its radius with a linear transformation medium. The traditional ...
Detecting Dependence in the Sensitive Parameter Space of a Model Using Statistical Inference and Large Forecast Ensembles
Publisher: American Meteorological Society
Abstract: his study looks for evidence of correlation among model physical parameters in the sensitive parameter space defined by those randomly sampled physical parameter vectors that induce the most notable response in some forecast ...
Postearthquake Decision Making on Sewer Recovery and the Roles of Damage and Repair Data: Case Study of Christchurch, New Zealand
Publisher: American Society of Civil Engineers
Abstract: Decision making on the reinstatement of the Christchurch sewer system after the Canterbury (New Zealand) earthquake sequence in 21–211 relied strongly on damage data, in particular closed circuit television (CCTV). This ...
Preparation and Distribution Analysis of Thermal Barrier Coatings Deposited on Multiple Vanes by Plasma Spray-Physical Vapor Deposition Technology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The multicomponent NiCoCrAlTaY coating as bond layer as well as the zirconia stabilized by yttrium oxide (YSZ) coating as top ceramic layer was deposited on duplex vane surface by plasma spray-physical vapor deposition ...
Interdecadal Variability in a Numerical Model of the Northeast Pacific Ocean: 1970–89
Publisher: American Meteorological Society
Abstract: Variations in the thermocline depth of the northeast Pacific Ocean during 1970?1989 are investigated using a reduced-gravity numerical model forced by the local surface wind stress and at the southern land-ocean boundary ...
A Multidimensional Model for Aerosols: Description of Computational Analogs
Publisher: American Meteorological Society
Abstract: The numerical algorithms which we use to simulate the advection, diffusion, sedimentation, coagulation and condensational growth of atmospheric aerosols are described. The model can be used in one, two, or three spatial ...
