Discussion: “Cavitation Damage to Centrifugal Pump Impellers During Operation With Liquid Metals and Molten Salt at 1050–1400 F” (Smith, P. G., DeVan, J. H., and Grindell, A. G., 1963, ASME J. Basic Eng., 85, pp. 329–335)
(The American Society of Mechanical Engineers (ASME), 1963) -
The Theory of Resonance in Hydropower Systems. Discussion of Incidents and Accidents Occurring in Pressure Systems
(The American Society of Mechanical Engineers (ASME), 1963)The opinion has been expressed that—in the past thirty years—the most severe and spectacular accidents have been caused by resonance in power conduits. If this appraisal is true, then there ... -
Measurements of Auto-Oscillation in a Hydroelectric Supply Tunnel and Penstock System
(The American Society of Mechanical Engineers (ASME), 1963)Severe sustained vibration of a closed hydraulic-turbine penstock valve was associated with accidentally inadequate inflation of the valve service seal. The vibration stopped when the valve bypass ... -
On the Prediction of Gas Flow Rates Through Round Wire Screens
(The American Society of Mechanical Engineers (ASME), 1963)A relatively simple expression is derived for the flow through round wire screens by considering the screen to be made up of a number of noninteracting cylinders and using classical data on ... -
Linearized ph Stability Theory for Translatory Half-Speed Whirl of Long, Self-Acting Gas-Lubricated Journal Bearings
(The American Society of Mechanical Engineers (ASME), 1963)The linearized ph approximation to the time dependent Reynolds equation is solved simultaneously with the equations of motion for a rotating journal shaft supported by a rigidly mounted bearing ... -
The Viscosity-Temperature-Pressure Relationship of Lubricating Oils and Its Correlation With Chemical Constitution
(The American Society of Mechanical Engineers (ASME), 1963)Viscosities of twenty well-defined, representative mineral-oil fractions have been determined at temperatures from 25 to 90 deg C (77 to 194 deg F) and at pressures up to about 1000 atmospheres ... -
The Shape of Creep Curves
(The American Society of Mechanical Engineers (ASME), 1963)The scatter of results in long time creep or rupture tests is such that the strongest sample can sustain a stress at least 50 percent higher than the weakest sample. A large part of this ... -
Elastic-Plastic Deformation of a Single Grooved Flat Plate Under Longitudinal Shear
(The American Society of Mechanical Engineers (ASME), 1963)The development of plastic strain is followed from the elastic through the partially plastic to the fully plastic condition for a nonstrainhardening material. Adjacent to the zone of deformation ... -
The Clamped Plate Analogy for Thermoelasticity
(The American Society of Mechanical Engineers (ASME), 1963)A method is described for determining the thermal stresses in plane systems with free boundaries. The method makes use of the analogy between the problems of the bending stresses in clamped ... -
Stress-Strain Distribution During Transient Heating of a Transversely Anisotropic Material
(The American Society of Mechanical Engineers (ASME), 1963)Four by six-in. transversely anisotropic plates of 1/8 and 1/4 -in-thick pyrolytic graphite were subjected to transient heating in an oxyacetylene flame apparatus. At temperatures up to 1500 deg ... -
Photothermoelastic Investigation of Thermal Stress in Flat Plates
(The American Society of Mechanical Engineers (ASME), 1963)Predictions of thermal stresses in various shape flat plates with a parabolic temperature field applied in one direction were found to yield good agreement with photothermoelastic analysis. A ... -
Fatigue Characteristics of Open-End Thick-Walled Cylinders Under Cyclic Internal Pressure
(The American Society of Mechanical Engineers (ASME), 1963)Thick-walled cylinder fatigue data due to cyclic internal pressure for open-end cylinders in the range of 103 to 105 cycles to failure and having a diameter ratio of 1.4 to 2.0 at a nominal ... -
Geometrical Effects in Strain Cycled Aluminum
(The American Society of Mechanical Engineers (ASME), 1963)Dimensional changes in the form of necking and bulging occur in the shape of cylindrical and hourglass commercially pure aluminum specimens subjected to axial push-pull cyclic loading. The present ... -
Low Cycle Fatigue Damage in Pressure-Vessel Materials
(The American Society of Mechanical Engineers (ASME), 1963)Strain-controlled tension-compression fatigue tests were performed on the ASTM pressure vessel steels, A302 and A225, to study the damage processes that lead to failure in low cycle fatigue. The ... -
On Cumulative Damage in Impulse Fatigue Tests
(The American Society of Mechanical Engineers (ASME), 1963)Experimental results are presented for fatigue failure of mild steel specimens under repeated application of lateral impulses; the cumulative damage effect as a result of stresses arising from ... -
A Critical Analysis of Crack Propagation Laws
(The American Society of Mechanical Engineers (ASME), 1963)The practice of attempting validation of crack-propagation laws (i.e., the laws of Head, Frost and Dugdale, McEvily and Illg, Liu, and Paris) with a small amount of data, such as a few single ... -
On the Crack Extension in Plates Under Plane Loading and Transverse Shear
(The American Society of Mechanical Engineers (ASME), 1963)The crack extension in a large plate subjected to general plane loading is examined theoretically and experimentally. It is found that under skew-symmetric plane loading of brittle materials the ... -
Stability of Unloaded Gas-Lubricated Bearings
(The American Society of Mechanical Engineers (ASME), 1963)This paper deals with a perfectly cylindrical, self-acting, gas-lubricated, and unloaded journal bearing. Complete stability criteria for the translational mode of oscillation are formulated and a ... -

Application of Flow and Stability Theory to the Design of Externally Pressurized Spherical Gas Bearings
(The American Society of Mechanical Engineers (ASME), 1963)Application of the flow theory of Laub and Norton [1] and the stability theory of Licht, Fuller, and Sternlicht [2] is made to the design of externally pressurized spherical gas bearings. ...
