(The American Society of Mechanical Engineers (ASME), 1974)Scanning electron micrographs of different types of commercial abrasive grains used in grinding are discussed. Surface topography is found useful, along with other physical and chemical properties, ... -
Displacement Consideration for a Ductile Propagating Fracture in Line Pipe
(The American Society of Mechanical Engineers (ASME), 1974)To date, the technically complex problem of arriving at an analysis for a running shear fracture in a gas-transmission line pipe has been primarily viewed by investigators in terms of an ... -
Model Experiments for Thermal Shock Fracture Behavior
(The American Society of Mechanical Engineers (ASME), 1974)Thermal shock fracture tests with specimens of simple geometry (plate and hollow cylinder) made from an appropriate model material, glass, were performed to investigate the behavior of cracks ... -
Pipe Deformation During a Running Shear Fracture in Line Pipe
(The American Society of Mechanical Engineers (ASME), 1974)Under sponsorship of the American Iron and Steel Institute, U. S. Steel Research has been conducting full-scale burst tests of large-diameter submerged-arc-welded line pipe to determine the ... -
The Design and Application of Shear Fracture Propagation Studies
(The American Society of Mechanical Engineers (ASME), 1974)Shear fracture propagation is studied using an analysis based upon the thermodynamic equilibrium of a constant velocity fracture. This equation is shown to describe the behavior of all full ... -
A Procedure for Verifying the Structural Integrity of an Existing Pressurized Wind Tunnel
(The American Society of Mechanical Engineers (ASME), 1974)This paper describes the application of material test, stress-fatigue-fracture mechanics analyses, nondestructive examinations and repairs to verify the structural integrity and the remaining cyclic ... -
An Interpretation of the Yoder-Griffis-Crooker Observations of Sustained-Load Cracking in Ti-6Al-4V
(The American Society of Mechanical Engineers (ASME), 1974)Their recent NRL report documents a substantial degradation in load carrying capability of partially cracked specimens of annealed Ti-6 Al-4V plate in a room air environment. In this paper, the ... -
