      N. P. Bailey (The American Society of Mechanical Engineers (ASME), 1965)
      An equation of state of the form u/pv = muk is developed where u is internal energy, p is pressure, v is specific volume, and m and k are constants over wide ranges of the variables. It ...

    • Primary Creep Design of Thick Tubes 

      E. M. Smith (The American Society of Mechanical Engineers (ASME), 1965)
      For thick tubes subjected to internal pressure, the estimation of creep-life by the cumulative damage criterion requires knowledge of the time variation of stress and strain at certain critical ...

    • Accelerations and Mean Trajectories in Turbulent Channel Flow 

      S. Irmay (The American Society of Mechanical Engineers (ASME), 1960)
      The author shows that even in steady uniform turbulent channel flow there exist on the average mean accelerations and forces acting on fluid particles. These are computed from the flow equations ...

    • Uniaxial Creep-Rupture Behavior of Low-Alloy Steel Under Variable Loading Conditions 

      R. M. Goldhoff (The American Society of Mechanical Engineers (ASME), 1965)
      One of the analytical tools most used by elevated-temperature designers is the log stress-log minimum creep-rate curve. The curve is normally constructed using at least three and preferably more ...

    • Effects of Repeated Loading and Moisture on the Fracture Toughness of SAE 4340 Steel 

      W. A. Van Der Sluys (The American Society of Mechanical Engineers (ASME), 1965)
      This investigation determined the combined effect of water vapor and repealed loading on slow crack growth and fracture toughness. Round notched bars of SAE 4340 steel with a Rockwell C hardness ...

    • The Effect of Quench Aging and Cyclic-Strain Aging on Low Carbon Steel 

      L. F. Coffin (The American Society of Mechanical Engineers (ASME), 1965)
      The present paper is an extension of a previous investigation, and considers the effects of various quench aging treatments on SAE 1010 and 1111 subjected to cyclic strain at aging temperatures. ...

    • Creep-Rupture Behavior of Unnotched and Notched Nickel-Base Alloys in Air and in Vacuum 

      P. Shahinian (The American Society of Mechanical Engineers (ASME), 1965)
      The influence of test atmosphere on creep-rupture properties was determined for plain and notched bars of nickel, Nichrome V, Udimet 500, and Inconel X. The rupture life of nickel and of ...

    • A Set of Fatigue Failure Criteria 

      H. O. Fuchs (The American Society of Mechanical Engineers (ASME), 1965)
      A set of three criteria is presented: One for crack nucleation, one for crack propagation, and one for yielding. In combination these three criteria simply explain known data on long-life ...

    • High Temperature Rupture, Fatigue, and Damping Properties of AISI Designation 616 (Type 422 Stainless) Steel
