Influence of Flow Stress and Friction Upon Metal Flow in Upset Forging of Rings and Cylinders
(The American Society of Mechanical Engineers (ASME), 1972)An upper-bound velocity field that considers bulging has been applied to cylinder and ring upsetting. Computer programs have been developed to (a) determine strain, strain rate, velocity, and ... -
Computer-Aided Visioplasticity Solution to Axisymmetric Extrusion Through Curved Boundaries
(The American Society of Mechanical Engineers (ASME), 1972)A procedure for smoothing the experimental values of the flow function ψ in axisymmetric extrusion through curved boundaries was developed. The analysis was applied to a 45 deg conical die ... -
Surface Profile Characterization by Autoregressive-Moving Average Models
(The American Society of Mechanical Engineers (ASME), 1972)The surface texture of a machined part is in general composed of three topographical components: waviness, roughness, and errors of form. A new technique for surface profile characterization is ... -
On the Metal Physical Considerations in the Machining of Metals
(The American Society of Mechanical Engineers (ASME), 1972)Experimental studies of plastic deformation produced during metal cutting have shown that a dynamic equilibrium is established between strain hardening and recovery during chip formation. ... -
Inclusion of a Support Friction Into a Computerized Solution of a Self-Compensating Pipeline
(The American Society of Mechanical Engineers (ASME), 1972)Thermal elongations of a pipeline are compensated in many cases by bending of pipeline branches. If the pipeline lies on a horizontal rough and flat foundation that bending is influenced by ... -
Analysis of Stress Concentrations in Thick Cylinders With Sideholes and Crossholes
(The American Society of Mechanical Engineers (ASME), 1972)An approximate theoretical analysis is presented for the determination of stress concentration factors in thick walled cylinders with sideholes and crossholes. The cylinders are subjected to both ... -
Radiation and Temper Embrittlement Processes in Advanced Reactor Weld Metals
(The American Society of Mechanical Engineers (ASME), 1972)Experimental weld filler metals having high resistance to radiation embrittlement at ≃550 F (288 C) have been developed for quenched and tempered A543 and A542 steel. The filler metals are ... -
Design of a Flash Stage for a Multistage Flash Evaporator
(The American Society of Mechanical Engineers (ASME), 1972)Two correlations are developed (for which there is precedent in the literature) interrelating the many process variables for adequate design of a flash stage. Both correlations are based on the ... -
A General Method for Kineto-Elastodynamic Analysis and Synthesis of Mechanisms
(The American Society of Mechanical Engineers (ASME), 1972)Kineto-elastodynamics is the study of the motion of mechanisms consisting of elements which may deflect due to external loads or internal body forces. This paper describes the initial phases ... -
An Experimental Study of Thermal Aspects of Cylindrical Plunge Grinding
(The American Society of Mechanical Engineers (ASME), 1972)The workpiece temperature in cylindrical plunge grinding is considered as a superposition of a base temperature and an interference zone temperature. A solution for the transient base temperature ... -
Analysis of Friction in Ring Compression: A Factorial Experiment
(The American Society of Mechanical Engineers (ASME), 1972)The influence of lubricant, rate of deformation, surface roughness, deformation, and temperature on the coefficient of friction of three types of aluminum were studied using ring-compression tests. ... -
An Analysis of Deformation Characteristics and Interfacial Friction Conditions in Simple Upsetting of Rings
(The American Society of Mechanical Engineers (ASME), 1972)Presented in this paper is an analytical investigation of the deformation characteristics at the outer equator and the change in diameter of the inner equator in simple upsetting of flat rings. ... -
A Rational Approach for Designing Gray Iron Components
(The American Society of Mechanical Engineers (ASME), 1972)Three suggested phases of improvement in the design methods for gray iron components are: (a) design based on accurate strength and deformation analyses, instead of the currently used elastic ... -
A Study of Temperature Gradients Inside a Horizontal Cylinder With Heated and Recirculated Diving Gas Mixtures
