Some Experiments on Dynamic and Quasi-Static Forging of Aluminum at Elevated Temperatures
(The American Society of Mechanical Engineers (ASME), 1973)The paper describes the results of hot and warm forging tests on aluminum specimens, using a modified Hopkinson pressure-bar in which impact velocities up to 100 m/s could be obtained. The ... -
Plastic Instability of Thin Shells Deformed by Rigid Punches and by Hydraulic Pressure
(The American Society of Mechanical Engineers (ASME), 1973)A theory has been developed to provide a solution for axisymmetrical shells in the plastic range for large deformations up to fracture. It includes the effects of strain history, nonlinear ... -
A Phenomenological Theory of Aging Effects of Metals
(The American Society of Mechanical Engineers (ASME), 1973)A constitutive law is developed for metals which have aging properties. The development of this law is based on the assumption that the mechanical properties of simple aging materials can be ... -
Factors Affecting Curling in Rolled Sheet
(The American Society of Mechanical Engineers (ASME), 1973)The influence of several rolling parameters on curling during the rolling of sheet was investigated. The material studied was primarily 0.5 in. thick 2024 aluminum. The factors studied were ... -
Elastic-Plastic Deformation in Edge-Notched Tension Specimens Under Plane Stress Conditions
(The American Society of Mechanical Engineers (ASME), 1973)An elastic-plastic, plane stress, finite element analysis has been performed on edge-notched tension members having elastic stress concentration factors of 2.28 and 3.06. For net section stresses ... -

Kinetics of Subcritical Crack Growth and Deformation in a High Strength Steel
(The American Society of Mechanical Engineers (ASME), 1973)The kinetics of subcritical crack growth under sustained loading in a chemically inert environment (dehumidified argon) and the companion deformation kinetics were determined to examine the possible ... -
Stress Rupture Behavior of a Dispersion Strengthened Superalloy
(The American Society of Mechanical Engineers (ASME), 1973)A dispersion strengthened nickel-base superalloy, designated IN-853, has been made by a new process called “Mechanical Alloying.” This provides a long sought combination of properties typical of ... -
The Dependence of the Notch Sensitivity of Waspaloy at 1000–1400 Deg F on the Gamma Prime Phase
(The American Society of Mechanical Engineers (ASME), 1973)The morphology of the gamma prime phase was correlated with the mechanical behavior of Waspaloy sheet at 1000–1400 deg F. “Overaging” eliminated time-dependent edge-notch sensitivity and produced ... -
Relationship of Mechanical Characteristics and Microstructural Features to the Time-Dependent Edge-Notch Sensitivity of Inconel 718 Sheet
(The American Society of Mechanical Engineers (ASME), 1973)Time-dependent notch sensitivity of Inconel 718 sheet was observed at 900 deg F to 1200 deg F (482–649 deg C). It occurred when edge-notched specimens were loaded below the yield strength and ... -
Rotating Band Pressures and Engraving Forces in 155mm Artillery Shells
(The American Society of Mechanical Engineers (ASME), 1973)The forces retarding the motion of 155mm artillery shells during quasi-static engraving of the rotating band were investigated both experimentally and analytically. The analytic method was based ... -
