Optimum Carbon Content for Tempered Martensitic Steels
(The American Society of Mechanical Engineers (ASME), 1968)Notch-tensile tests were conducted on four quenched and tempered steels to study the effect of carbon content on notch toughness. The toughness was found to decrease when the carbon content ... -

Some Properties of Laminar Boundary Layers on Curved Surfaces
(The American Society of Mechanical Engineers (ASME), 1968)Equations have been developed [1] which describe the flow in a steady, two-dimensional, incompressible, laminar boundary layer on a curved surface. The method of “similar solutions” yields a ... -
Ductile Creep Rupture of Shells With Strain Hardening and Time-Dependent Loading
(The American Society of Mechanical Engineers (ASME), 1968)This paper presents an analysis of the tensile instability phenomenon in a thin-walled membrane shell of revolution undergoing creep while subjected to a time-dependent internal pressure. ... -
On the Stresses Near an Oblique Elliptical Aperture in a Large Plate
(The American Society of Mechanical Engineers (ASME), 1968)An experiment was performed to determine the nature of the elastic stress system in the vicinity of an elliptical aperture in a plate subjected to uniform in-plane uniaxial tension, when the ... -
Flow Stress of 6061 AL Alloy Composites
(The American Society of Mechanical Engineers (ASME), 1968)The relationship of flow stress to the interparticle path of two phase alloy systems is discussed and the similarity of two phase alloy systems to wire or fiber reinforced composites is ... -
A Biaxial Fracture Criterion for Porous Brittle Materials
(The American Society of Mechanical Engineers (ASME), 1968)The Griffith criterion for fracture of brittle materials is based on a model of a continuum in which infinitely sharp cracks are distributed with random orientations. This study extends the ... -
The Turbulent Wake of a Body of Revolution
(The American Society of Mechanical Engineers (ASME), 1968)The wake behind a six-to-one spheroid was studied for a Reynolds number equal to 2.75 × 106 at 12 sections from 0.25 dia upstream to 18 dia downstream from the stern of the body. The ... -
Two Models for Cavity Flow—A Theoretical Summary and Applications
(The American Society of Mechanical Engineers (ASME), 1968)A summary is given of two-dimensional, steady-state, nonlinear theory for two finite-cavity models and their solutions. Two applications are described. First, the influence of the foil’s depth ... -
Effects of Gravity and Surface Tension Upon Liquid Jets Leaving Poiseuille Tubes
(The American Society of Mechanical Engineers (ASME), 1968)A method is developed for approximating the transverse velocity component in the incompressible two-dimensional boundary layer equations. The method is restricted to flows that are symmetrical in ... -
Secondary Flow Effects in a Bounded Rectangular Jet
(The American Society of Mechanical Engineers (ASME), 1968)The isotach pattern in a bounded jet with an aspect ratio of 6 suggests the presence of a secondary flow structure. A physical flow model is presented, and further measurements substantiate ... -
Rough Surface Effects on Cavitation Inception
(The American Society of Mechanical Engineers (ASME), 1968)Cavitation inception and the associated bubble dynamics in turbulent boundary layers adjacent to surfaces roughened with triangular grooves is investigated in a two-dimensional recirculating water ... -
Computerized Method of Characteristics Calculations for Unsteady Pneumatic Line Flows
(The American Society of Mechanical Engineers (ASME), 1968)Prior to development of high-speed digital computers, the method of characteristics has not been readily available for pneumatic system design. The traditional organization of computations on a ... -
Mode Oriented Design Viewpoint for Linear, Lumped-Parameter Multivariable Control Systems
(The American Society of Mechanical Engineers (ASME), 1968)There are multivariable systems which have free motions dominated by a limited number of clearly separable modes. In some cases it is possible to specifically control these modes, thereby ... -
Optimum Linear Preview Control With Application to Vehicle Suspension
(The American Society of Mechanical Engineers (ASME), 1968)The concept of preview control (a control scheme in which an input is sensed before it reaches the controlled plant) is discussed and applied to the guidance of vehicles over statistically ... -
New Liapunov Function for Nonlinear Time-Varying Systems
(The American Society of Mechanical Engineers (ASME), 1968)A new method of generating Liapunov functions is described that is useful for time-varying nonlinear differential equations. Constant coefficient quadratic forms are often used as Liapunov functions ... -
Aspects of Adaptive Optimal Steady-State Control
(The American Society of Mechanical Engineers (ASME), 1968)The paper extends and modifies an approach to adaptive optimal control problems proposed by Kulikowski. The emphasis at the outset is placed upon optimizing the steady-state system performance ...
