Velocities of Fragments From Bursting Gas Reservoirs
(The American Society of Mechanical Engineers (ASME), 1971)A solution is obtained from a simplified approach for the problem of the motion of two fragments driven into a vacuum after rupture of a container filled with gas. Following rupture, the two ... -
Fatigue Crack Growth in Type 316 Stainless Steel at High Temperature
(The American Society of Mechanical Engineers (ASME), 1971)The dependence of fatigue crack growth rates on range of stress intensity factor (ΔK) in Type 316 stainless steel was investigated over the temperature range of 75 to 1100 deg F. The data ... -
Thermal Stresses in Thick-Walled Circular Cylinders Under Axisymmetric Temperature Distribution
(The American Society of Mechanical Engineers (ASME), 1971)A series solution is obtained for thick-walled cylinders subjected to a temperature distribution which varies both radially and axially. The solution is based on three-dimensional linear theory ... -
The Effective Utilization of Yield Strength
(The American Society of Mechanical Engineers (ASME), 1971)In many structural and constructional applications (such as pressure vessels), steels, particularly high-yield-strength steels, are not being utilized as effectively as may be possible. This occurs ... -
Stress Concentration in a Cylindrical Shell Containing a Circular Hole
(The American Society of Mechanical Engineers (ASME), 1971)The state of stress in a cylindrical shell containing a circular cutout was determined for axial tension, torsion, and internal pressure loading. The solution was obtained for the shallow shell ... -
Procurement of Safe Viewports for Hyperbaric Chambers
(The American Society of Mechanical Engineers (ASME), 1971)Lack of ASME Pressure Vessel Code Standards for the selection of material, designs, fabrication techniques, and prooftesting methods for viewports in hyperbaric chambers makes it mandatory that ... -
