The Influence of Higher Modes and Support Gaps on the Seismic Response of Piping Systems Containing Snubbers
(The American Society of Mechanical Engineers (ASME), 1997)In this study of flexible piping systems (0.6 to 6.6 Hz), it was shown that the fundamental mode was not always the most significant mode of vibration. This study also concluded that variations ... -
Optimal Design of Laminated Cylindrical Pressure Vessels for Maximum External Pressure
(The American Society of Mechanical Engineers (ASME), 1997)Finite element solutions are presented for the optimal design of hemispherically and flat-capped symmetrically laminated pressure vessels subjected to external pressure. The effect of vessel length, ... -
Technical Basis for Flawed Cylinder Test Specification to Assure Adequate Fracture Resistance of ISO High-Strength Steel Cylinder
(The American Society of Mechanical Engineers (ASME), 1997)High-pressure industrial gases (such as oxygen, nitrogen, argon, hydrogen, etc.) are stored and transported in portable cylinders. ISO TC58 SC3 has developed a draft specification 9809 for design ... -
Rigid-Plastic Deformation of a Ring-Stiffened Shell Under Blast Loading
(The American Society of Mechanical Engineers (ASME), 1997)An approximate solution for the plastic deformation of a ring-stiffened cylindrical shell in response to a nonaxisymmetric, exponentially decaying pressure load, is presented. The analogy between ... -
On Free Vibrations of an Embedded Anisotropic Spherical Shell
(The American Society of Mechanical Engineers (ASME), 1997)In this paper, free vibrations of a spherically isotropic spherical shell embedded in an elastic medium of Pasternak type are studied by using a six-mode shell theory that includes effects of ... -
Stress Concentration, Stress Intensity, and Fatigue Lifetime Calculations in Autofrettaged Tubes Containing Axial Perforations Within the Wall
(The American Society of Mechanical Engineers (ASME), 1997)Elastic, elastic-plastic and experimental stress analyses, and fatigue lifetime predictions are presented for thick cylinders containing multiple, axial holes within the wall. The holes are generally ... -
Prediction of Failures of Low-Pressure Steam Turbine Disks
(The American Society of Mechanical Engineers (ASME), 1997)Localized corrosion phenomena, including pitting corrosion, stress corrosion cracking, and corrosion fatigue, are the principal causes of corrosion-induced damage in electric power-generating facilities ... -
Axisymmetric Guided Wave Scattering by Cracks in Welded Steel Pipes
(The American Society of Mechanical Engineers (ASME), 1997)Scattering of axisymmetric guided waves by cracks and weldments of anisotropic bonding material in welded steel pipes is investigated in this paper by a hybrid method employing finite element ... -
A Boundary Integral Approach to Attachment/Spherical Shell Interaction
(The American Society of Mechanical Engineers (ASME), 1997)In pressure vessel applications, the accurate evaluation of the state of stress in the vicinity of nozzles or rigid attachments is of vital importance to the structural integrity of the vessel. ... -
Uncertainty Analysis in Quantitative Risk Assessment
(The American Society of Mechanical Engineers (ASME), 1996)Of the quantitative approaches applied to inservice inspection, failure modes, effects,criticality analysis (FMECA) methodology is recommended. FMECA can provide a straightforward illustration of how ... -
Behavior of a Tapered Hub Flange With a Bolted Flat Cover in Transient Temperature Field
(The American Society of Mechanical Engineers (ASME), 1996)An experimental and analytical study was made on a bolted connection subjected to thermal loading. The connection consists of an aluminum alloy tapered hub flange and a flat cover, including ... -
