Stress Solution for an Infinite Plate Containing Two Arbitrary Circular Holes Under Equal Biaxial Stresses
(The American Society of Mechanical Engineers (ASME), 1968)A method of successive approximations utilizing analytic stress functions of the complex variable z, in the manner of the Schwartz Alternating Method, has been used to obtain the solution of ... -
Fatigue-Crack Growth-Rate Studies of Low-Alloy Pressure-Vessel Steels
(The American Society of Mechanical Engineers (ASME), 1968)Fatigue-crack growth rates were determined at room temperature for ASTM A302-Class B and A 508-Class 2 steels in two characteristic plate and forging directions. Tests were performed under ... -
Elastic Stability of Circular Tubes of Circumferentially Variable Thickness Under External Pressure
(The American Society of Mechanical Engineers (ASME), 1968)The effect of circumferential variation in wall thickness on the elastic stability of long, thin-walled, circular tubes under external pressure is investigated both theoretically and experimentally. ... -
Assessment of the Plastic Strength of Pressure Vessel Nozzles
(The American Society of Mechanical Engineers (ASME), 1968)Theoretical developments on limit pressures of shells are cited and briefly discussed. Calculated limit pressure from several of the theoretical analyses are compared with numerous tests on radial ... -
Prevention of Sulfide-Stress Cracking in Sour-Condensate Well Equipment
(The American Society of Mechanical Engineers (ASME), 1960)Several case histories of equipment failures in sour-condensate wells are presented, reasons for these failures are discussed, and means for avoiding such failures are suggested. -
Short Transverse Properties of Certain High-Strength Steels
(The American Society of Mechanical Engineers (ASME), 1968)Attention has been paid in Naval Construction Research Establishment to the importance of problems arising from the presence of small nonmetallic inclusions in high-strength, low-alloy structural ... -
Prediction of Low-Cycle Fatigue Life of Specimens With Fabrication Flaws
(The American Society of Mechanical Engineers (ASME), 1968)A modification of the notch stress procedure for fatigue-life analysis is presented. The importance of considering the mechanics of the specimen and the effects of the notch on specimen mechanics ... -
Buckling and Lateral Vibration of Drill Pipe
(The American Society of Mechanical Engineers (ASME), 1968)Critical buckling loads and natural frequencies of lateral vibration modes are determined for a long vertical pipe, suspended in a fluid, simply supported at the top and vertically guided at ... -
Vapor-Liquid Separation at Supersonic Velocities
(The American Society of Mechanical Engineers (ASME), 1968)When a gas mixture at high pressure is expanded to a lower pressure, autorefrigeration often causes some of the heavier components to liquefy. This paper presents a new method for separating ... -
Mass Transfer Cooling on a Porous Flat Plate in Carbon-Dioxide and Air Streams
(The American Society of Mechanical Engineers (ASME), 1968)Heat transfer results are reported for a transpiration cooled porous flat plate placed in a stream of air and in a stream of CO2 . The tests were performed at a Mach number of 1.96 over ... -
A Method of Estimating the Optimum Mean Life of Plant Groups
(The American Society of Mechanical Engineers (ASME), 1968)This paper describes a method of optimizing average service life of plant groups. The method is stochastic or statistical rather than deterministic, in the sense that a time-frequency distribution ... -
Experimental Investigation of Creep Buckling of Circular Cylindrical Shells Under Axial Compression and Bending
(The American Society of Mechanical Engineers (ASME), 1968)The results are presented of an experimental investigation of creep buckling of circular cylindrical shells. The test specimens, manufactured from an aluminum alloy similar to 24S, had radius ... -
