Engraving Pressures for Cannelured Rotating Bands: Theoretical Investigation of the Indentation Pressure for Rectangular Metal Bands Unequally Supported on the Two Sides

摘要

The mathematical theory of ideal plasticity has been used to find an upper bound on the initial normal engraving pressure for a rectangular band of metal, set into a rigid encasement to different heights on the two sides„ This result gives an improved estimate of the engraving pressures on cannelured rotating bands by the device of viewing the "islands" between cannelures as small bands in them¬selves.
