Dislocation damping in copper single crystals
(1963)
Hysteresis loops were observed in 99.999 % pure copper single crystals under unidirectional cyclic stressing using a capacitance gage microstrain measuring technique. These loops; which represent an energy loss presumably ...
Bending of composite cylinders
(1969)
A study is made with the purpose of investigating the behavior of composite cylinders under the action of bending loads. A theoretical approach is proposed in which several simplifying assumptions are made, and an experimental ...
Unsteady laminar flow in a circular pipe
(1965)
An exact solution of unsteady laminar flow of an incompressible fluid in a circular pipe is presented. The flow is taken to be axially symmetric and parallel to the pipe axis. The equation of motion in two independent ...
Wall pressure distributions for a turbulent attacked jet flow
(1969)
In this study a method was developed to predict the pressure distribution along the enclosed wall in a turbulent attached jet flow. The flow was assumed two dimensional and only time averaged properties were considered. A ...
The stresses in a flat circular ring with a through-cut
(1963)
This thesis treats a new approach to the problem of a complete ring, with one cut, supported on one face of the cut and subjected to a non-self-equilibrating load. A standard method of approach makes use of the Fourier ...
Basic relation for the recovery of oil by steam application to an oil and hot water system
(1965)
A system of equations describing the general behavior of a "steam flood" or oil displacement by means of steam in a homogeneous, one-dimensional non-capillary model formation is here derived. An aspect of the steam flood ...
Forces required to roll an idealized drill bit across a Coulomb plastic material
(1968)
This thesis presents a systematic method for determining the forces on a simplified roller bit. The kinematics of an actual roller bit drilling in rock is complex; nevertheless, it is desirable to obtain an accurate ...
Characteristics of supersonic thrust nozzles for low density plasmas
(1962)
The thrust characteristics of a conical nozzle were experimentally determined using helium, partially ionized by a high energy electric arc, as the working fluid. The thrust produced in the supersonic section of the nozzle ...
Crossed-field acceleration of a supersonic plasma
(1963)
An effort was made to obtain further correlation between theoretical and experimental results for continuous Lorentz force acceleration of a partially ionized gas. Four different nozzle-accelerator combinations were evaluated ...
A lumped parameter approach to longitudinal and torsional vibrations of oil well drill strings
(1962)
The effect of tool joints on the passage of plane longitudinal and torsional waves along a drill pipe was studied. An approximate solution to the governing equations of motion found, and an idealized tool joint constructed. ...
