A Comparison of the Initiation With the Rapid Propagation of a Crack in a Mild Steel Plate
(The American Society of Mechanical Engineers (ASME), 1965)Recent indications of a direct proportionality between plane strain fracture toughness KIc and the strain hardening exponent n provide a new basis for comparing the initiation with the propagation ... -
Low Cycle Fatigue Life of Turbine Generator Retaining Rings Determined by Stress Cycling Tests
(The American Society of Mechanical Engineers (ASME), 1965)In a turbine generator rotor, the field winding extensions beyond the main body of the rotor forging are supported by high strength retaining rings, which are the most highly stressed components ... -
Thermal Fatigue of a Nickel-Base Alloy
(The American Society of Mechanical Engineers (ASME), 1965)The results of conventional (Coffin-type) thermal-fatigue tests of Hastelloy N are reported. The plastic-strains induced by thermal stresses ranged from a hundred micro-units to more than ten-thousand ... -
An Interpretation of the Mechanics of Crack Growth by Fatigue
(The American Society of Mechanical Engineers (ASME), 1965)A theory for the growth of cracks by fatigue is developed that is analogous to the brittle fracture of high strength materials. It is argued that it is possible to describe crack growth ... -
Gas-Lubricated Stepped Thrust Bearing—A Comprehensive Study
(The American Society of Mechanical Engineers (ASME), 1965)The theoretical part of this report is based on Ausman’s analysis [2] of gas-lubricated stepped slider bearings, but presented in simpler form. Experimental data in this paper verify Ausman’s ... -
Solution of the Stability Problem for 360 Deg Self-Acting, Gas-Lubricated Bearings
(The American Society of Mechanical Engineers (ASME), 1965)This is an investigation of the stability of self-acting, gas-lubricating bearings. Two approaches to the solution are presented and their results are compared. Also, the relation is discussed ... -
Misalignment Torques of Hydrodynamic Gas-Lubricated Journal Bearings
(The American Society of Mechanical Engineers (ASME), 1965)Design curves for misalignment torques are presented which are valid for high eccentricity ratios. Instead of perturbation analysis, numerical analysis is used to solve the governing Reynolds ... -
Stability Analysis of Gas-Lubricated, Self-Acting, Plain, Cylindrical, Journal Bearings of Finite Length, Using Galerkin’s Method
(The American Society of Mechanical Engineers (ASME), 1965)This paper extends the method of Cheng and Trumpler [5] to study stability of plain cylindrical gas journal bearings of finite length. Both equilibrium and stability results have been obtained. -
