Venturi Meter With Separable Diffuser
(The American Society of Mechanical Engineers (ASME), 1969)The effects on venturi meter efficiency and discharge coefficient of a radial, outward step at the transition from throat to diffuser are reported over a Reynolds number range of 1 × 104 ... -
Dynamic Tear Test Definition of the Temperature Transition From Linear Elastic to Gross Strain Fracture Conditions
(The American Society of Mechanical Engineers (ASME), 1969)Transition temperature concepts for fracture-safe design have been based on the relatively narrow temperature range evidenced by the fracture mode transition from plane strain to plane stress. ... -
Index Method for Pumping Operation of Reversible Pump-Turbine
(The American Society of Mechanical Engineers (ASME), 1969)The adaptability of the Winter-Kennedy index method [1] was examined, and consequently “Draft Tube Index Method” for Francis and diagonal flow pump-turbines under pumping operation were newly ... -
Pulsatile Flow Behavior in Elastic Systems Containing Wave Reflection Sites
(The American Society of Mechanical Engineers (ASME), 1969)An analytical study is presented for one-dimensional, pulsatile flow of an incompressible fluid in systems of elastic tubing. Nonlinear terms are retained in the system of describing equations. ... -
Thermal Entry for Low Reynolds Number Turbulent Flow
(The American Society of Mechanical Engineers (ASME), 1969)The thermal entrance problem for low Reynolds number, turbulent flow of gases in circular tubes is solved analytically by the method of Sparrow, Hallman, and Siegel. Fluid properties are ... -
Low Density Nozzle Flow
(The American Society of Mechanical Engineers (ASME), 1969)Experimental data are presented for the flow of argon in a converging nozzle in the continuum, slip, and free molecular regimes. The data are plotted in a number of ways so as to show ... -
On the Interaction of Intense Acoustic Fields and Viscous Fluid Flows
(The American Society of Mechanical Engineers (ASME), 1969)A survey is given of several analytical techniques that can be applied to acoustic streaming phenomena. A method is selected for examining intense acoustic field-viscous fluid flow interaction ... -
Initial Development of Turbulent, Compressible Free Shear Layers
(The American Society of Mechanical Engineers (ASME), 1969)The mixing zone between a two dimensional free stream and a fluid essentially at rest is studied experimentally and analytically. Turbulent shear layer velocity profiles were measured behind ... -
Investigation of the Relaxation of Residual Stresses in Autofrettaged Cylinders
(The American Society of Mechanical Engineers (ASME), 1969)Autofrettaged cylinders have been restricted in their use to relatively low temperatures because of the stress relieving effect of high temperatures. Thus, it was felt that high-temperature ... -
A Reaction-Rate Treatment of the Extrapolation Methods in Creep Testing
(The American Society of Mechanical Engineers (ASME), 1969)Various phenomenological equations for the dependence of the time-to-rupture, etc., on temperature and stress have been related to a generalized equation based on chemical reaction-rate theory. ... -
A Reaction-Rate Treatment of the Life Fraction Hypothesis in Creep Testing
(The American Society of Mechanical Engineers (ASME), 1969)The equation describing Robinson’s life fraction hypothesis has been derived from a generalized equation based on chemical reaction-rate theory. It is shown what further assumptions are needed ... -
Double-Notch Creep Rupture of 5 Cr-0.5 Mo Steels
(The American Society of Mechanical Engineers (ASME), 1969)Following up their earlier work on unnotched and single-notched specimens of 5 Cr-0.5 Mo steel, the authors investigated the change in notch profile and dimensions, as well as the structural ... -
Alloy Steel Dynamic Strain-Aging and Notch Brittle Fracture
(The American Society of Mechanical Engineers (ASME), 1969)Transverse V-notch Charpy specimens prepared from sheet bar of 1045, 4140, and 4340, each in four different metallurgical conditions, were deformed to fracture in slow bending at four diverse ... -
Neck-and-Split Tensile Fracture of Anisotropic Plate Steel
(The American Society of Mechanical Engineers (ASME), 1969)Rolling-direction tensile specimens of 0.31 C quenched and tempered alloy plate steel displayed cup-and-cone, split-layered, neck-and-split, and square-break fracture configurations over distinct ... -
Very-Short-Time, Very-High-Temperature Creep Rupture of Type 347 Stainless Steel and Correlation of Data

Low-Cycle Fatigue Behavior Under Biaxial Strain Distribution
(The American Society of Mechanical Engineers (ASME), 1969)This paper presents a linear cumulative damage theory considering macroscopically both elastic and plastic straining to define behavior in the low-cycle fatigue region of the classic S-N curve. ... -
Biaxial Residual Surface Stresses From Grinding and Finish Machining 304 Stainless Steel Determined by a New Dissection Technique
(The American Society of Mechanical Engineers (ASME), 1969)A new technique for measuring residual surface stresses in metals is described. This technique, which is based on the dissection method, yields detailed biaxial residual stress distributions. ... -
A General Theory of Fatigue Damage Accumulation
(The American Society of Mechanical Engineers (ASME), 1969)The aim of this presentation is to develop a general linear theory of isotropic cumulative failure. This involves a phenomenological consideration of fatigue damage accumulation under very general ... -
