Downhole Measurements of Thermal Conductivity in Geothermal Reservoirs
(The American Society of Mechanical Engineers (ASME), 1977)The line source method of determining thermal conductivity is extended to include the transient effect associated with the fluid in flowing geothermal wells. The general equations describing ... -
Geothermal Energy: Heat Extraction From Hot Dry Rock Masses
(The American Society of Mechanical Engineers (ASME), 1977) -
Seals for Geothermal Roller Drill Bits
(The American Society of Mechanical Engineers (ASME), 1977)A significant factor contributing to short bit life and attendant high costs for geothermal drilling is the lack of seals for elevated temperatures. To assist development of a high-temperature ... -
Geothermal Drill Bit Improvement—Specific Application to the Geysers
(The American Society of Mechanical Engineers (ASME), 1977) -
Origin and Spacing of Cleats in Coal Beds
(The American Society of Mechanical Engineers (ASME), 1977)Cleats are natural fractures in coal beds resulting from dehydration, devolatilization, and stresses in the earth’s upper crust during coalification. The orientation of these fractures usually ... -
Accuracies of Numerical Solution Methods for the Elastic-Perfectly Plastic Model
(The American Society of Mechanical Engineers (ASME), 1977)The accuracy of integration of the constitutive equations for an isotropic elastic-perfectly plastic von Mises material is examined. A strainrate vector of arbitrary direction, but constant in ... -
Decoupling of Undamped Vibration Systems
(The American Society of Mechanical Engineers (ASME), 1977)Decoupling of a multimass vibration system from a large structure is investigated. First the dynamic influence on the foundation (or floor) response spectra of the inertia of the subcomponent ... -
An Energy-Based Fatigue and Creep-Fatigue Damage Parameter
(The American Society of Mechanical Engineers (ASME), 1977)A general damage parameter for fatigue and creep-fatigue applications based on the hypothesis that damage is dependent on the internal total octahedral strain energy is derived. This general ... -

The Compression of Thick-Walled Tubes by External Pressure
(The American Society of Mechanical Engineers (ASME), 1977)In a previous work the author enunciated a procedure for the analysis of tension specimen subjected to high pressure. Utilizing these results to define the work-hardening function the present ... -
Chairman’s Report on the Panel Discussion on High-Temperature Design: At the Third International, Conference on Pressure Vessel Technology, Tokyo, Japan, April 19–22, 1977

Experimental Stress Analysis for Four 24-in. ANSI Standard B16.9 Tees
(The American Society of Mechanical Engineers (ASME), 1977)This paper describes the experimental stress analysis of low cycle fatigue tests of four tees tested by Combustion Engineering, Inc. (C-E) under subcontract to Union Carbide Nuclear Division. ... -
Limit Design of Perforated Cylindrical Shells per ASME Code
(The American Society of Mechanical Engineers (ASME), 1977)Limit pressures are evaluated for cylindrical perforated shells containing circular holes arranged in the various penetration patterns typically found in practice. Statically admissible discontinuous ... -
