Calculations of Added Mass and Damping Coefficients for Hexagonal Cylinders in a Confined Viscous Fluid
(The American Society of Mechanical Engineers (ASME), 1980)A finite element model is formulated and computations performed for the hydrodynamic reactions of harmonically oscillating hexagonal cylinders in an incompressible, viscous fluid. Regular hexagonal ... -
Vortex-Excited Cross-Flow Vibrations of a Single Cylindrical Tube
(The American Society of Mechanical Engineers (ASME), 1980)The cross-flow vibrations of a single tube are considered in this paper, for incident flows of air and water. Recent experimental measurements of the resonant response of and fluid dynamic ... -
Prevention and Cure of Flow-Induced Vibration Problems in Tubular Heat Exchangers
(The American Society of Mechanical Engineers (ASME), 1980)Various methods for predicting and solving tube and acoustic vibration problems in heat exchangers in cross flow are presented: the use of stability diagrams comprising in-service experience of ... -
Small-Scale Yielding at the Tip of a Through-Crack in a Shell
(The American Society of Mechanical Engineers (ASME), 1980)Deformation theory is used to model plastic deformation at the tip of a through-crack in a thin shell. In the vicinity of the crack the shell is subjected to both stretching and bending, ... -
An LEFM Analysis for the Effects of Weld-Repair-Induced Residual Stresses on the Fracture of the HSST ITV-8 Vessel
(The American Society of Mechanical Engineers (ASME), 1980)A fracture mechanics analysis for an intermediate size pressure vessel is described. The vessel was tested as part of the Heavy Section Steel Technology program at Oak Ridge National Laboratory. ... -
An Analysis Procedure for Predicting Weld Repair Residual Stresses in Thick-Walled Vessels
(The American Society of Mechanical Engineers (ASME), 1980)An analysis procedure for computing residual stresses due to weld repairs of heavy steel sections is described and illustrated. The model has several unique features for weld repair applications. ... -
Fatigue Threshold Stress Intensity and Life Estimation of ASTM—A106B Piping Steel
(The American Society of Mechanical Engineers (ASME), 1980)Fatigue design curves extending to 1010 cycles do not exist for A106B and A155KC70 piping steels. Therefore, a fracture mechanics approach which uses the concept of threshold stress intensity ... -
A Simplified Approach to Creep Buckling of Structures Under Varying Loads
(The American Society of Mechanical Engineers (ASME), 1980)A critical strain approach to the prediction of creep buckling time in structures under varying loads is investigated and its relationship with the conventional linear cumulative damage (life-fraction) ... -

Design of Conical Shells Under External Loads
(The American Society of Mechanical Engineers (ASME), 1980)The background is presented for the rules for conical shells and reducers under external pressure which were recently added to Section VIII, Division 1. A simplified method for the design of ... -
Relationships Between Mechanical Properties and the Extension and Arrest of Unstable Cracks in Line Pipe Steels
(The American Society of Mechanical Engineers (ASME), 1980)With the increasing need for high-strength, high-pressure, large-diameter, gas-transmission lines, considerable attention has been given, in recent years, to the aspects of fracture initiation, ... -
Simulation of Partial Autofrettage by Thermal Loads
(The American Society of Mechanical Engineers (ASME), 1980)The effect of favorable residual stresses of an autofrettaged tube is well known [1]. In many instances there is redistribution of these stresses due to changes of geometrical configurations ... -
On Wake-Induced Flutter of a Circular Conductor in the Wake of Another
(The American Society of Mechanical Engineers (ASME), 1980)This paper, which is an extension of [1] , treats two-dimensional aeroelastic stability of two coupled conductors. It is found that the wake-induced flutter is symmetric with respect to the ... -
