Investigation of Warm Prestress for the Case of Small ΔT During a Reactor Loss-of-Coolant Accident
(The American Society of Mechanical Engineers (ASME), 1979)An experimental investigation was conducted to characterize the benefits of warm prestress (WPS) in limiting crack extension in the wall of a nuclear vessel during a LOCA-ECCS. The present ... -
Plastic Collapse of Thin Internally Pressurized Torispherical Shells
(The American Society of Mechanical Engineers (ASME), 1979)The plastic collapse pressures of internally pressurized thin torispherical shells are given in the present paper. The influence of both the geometric parameters (i.e., r/D, RS /D and D/t) and ... -
Consistent Creep and Rupture Properties for Creep-Fatigue Evaluation
(The American Society of Mechanical Engineers (ASME), 1979)The currently accepted practice of using inconsistent representations of creep and rupture behaviors in the prediction of creep-fatigue life is shown to introduce a factor of safety beyond that ... -
Verification of Specimens for Low-Cycle Fatigue and Cyclic Plasticity Testing
(The American Society of Mechanical Engineers (ASME), 1979)The results of inelastic finite element analyses of several uniaxial specimens used for low-cycle fatigue and cyclic plasticity testing are presented. The test specimens studied include both ... -
Development of Fatigue Design Curves for Pressure Vessel Alloys Using a Modified Langer Equation
(The American Society of Mechanical Engineers (ASME), 1979)The Jaske and O’Donnell [1 ] curve-fitting procedure for analyzing fatigue data generated between room temperature and 427° C (800° F) for several pressure vessel alloys is reexamined ... -
Inelastic Bending of Beams Under Time-Varying Moments—A State Variable Approach
(The American Society of Mechanical Engineers (ASME), 1979)The inelastic response of a beam to several time-varying moments is presented in this paper. The constitutive equations used to describe the beam material are due to Hart. This is one of ... -

Thermoelastic Analysis of Nonaxisymmetrically Heated Thick Cylindrical Shells
(The American Society of Mechanical Engineers (ASME), 1978)The thermoelastic problem of a thick cylinder subjected to nonaxisymmetric temperature distribution is considered. The temperature distribution may be harmonic or non-harmonic. The problem is ... -
Increasing the Fracture Resistance of Cemented Carbides During the Drilling of Iron Ores
(The American Society of Mechanical Engineers (ASME), 1978)Investigation shows that there is a preferred cobalt content for a given hardness of a cemented carbide insert when used in a bit which is drilling iron ore. Two parameters determine the ... -

Lower-Bound Limit Pressures for the Cylinder-Cylinder Intersection: A Parametric Survey
(The American Society of Mechanical Engineers (ASME), 1978)Lower-bound limit pressures are presented for the case of a flush radial cylindrical nozzle in a cylindrical vessel under internal pressure. A comprehensive range of parameters has been covered ... -
An Improved Basis for Formulating Acceptance Criteria for Structural Welds
(The American Society of Mechanical Engineers (ASME), 1978)Improvements in current weld acceptance criteria can be achieved if the standards are derived from structural reliability and integrity considerations. These criteria require an assessment of the ... -

A Motion Analysis of a Riser Upper Joint Interacting With a Floating Vessel
(The American Society of Mechanical Engineers (ASME), 1978)Riser motions (acceleration and velocity) should be estimated for the determination of forces on the riser in waves. They are predominantly influenced by vessel motions. Previous analyses involving ... -
Evaluation of Steel Plate Quality by Through Thickness Testing
(The American Society of Mechanical Engineers (ASME), 1978)The mechanical properties and degrees of isotropy of SA-516 grade 70 plate steels produced by conventional, ladle flux-treated, calcium-treated, and electroslag remelting procedures were characterized ... -

Mathematical and Experimental Investigation Into the Auto-Frettaging of High-Pressure Mudpump Fluid Ends
(The American Society of Mechanical Engineers (ASME), 1978)The fluid ends on high-pressure triplex mud pumps are exposed to high cyclic internal pressures. These fluid ends should therefore have adequate elastic strength and fatigue life under operating ...
