    • Variation of Yield Stress With Strain and Strain Rate in Mild Steel 

      H. Inhaber (The American Society of Mechanical Engineers (ASME), 1967)
      Knowledge of the yield stresses characterizing steel strip is essential to a correct discussion of the cold rolling process. Various authors have noted that yield stress rises, in general, with ...

    • Estimated Roll Bite Temperatures Encountered in Cold Rolling, and Their Effect in Rolling 

      H. Inhaber (The American Society of Mechanical Engineers (ASME), 1967)
      In modern cold rolling, strip exit velocities of the order of thousands of feet per minute are employed. Even if only moderate reductions of the strip are performed, large amounts of heat ...

    • Fracture of Abrasive Grain in Grinding 

      N. S. Eiss (The American Society of Mechanical Engineers (ASME), 1967)
      The fracture strength of single grits of alumina abrasive grain, as observed while cutting mild steel, was measured as a function of the grain depth of cut, the tangential force during cutting, ...
