Abstract:

Using a method developed by the authors, the configuration of the inside boundary of circular rings, subjected to diametral compression, has been optimized, keeping cleared the space enclosed by the original circular inside boundary. The range of diameters studied was 0.33 IDOD 0.7. In comparison with circular rings of the same IDOD, the stress concentrations have been reduced by about 30, the weight has been reduced by about 10 and coefficients of efficiency of about 0.96 have been attained. The maximum values of compressive and tensile stresses on the edge of the hole, and sharp corners exhibit zero stress. The geometries for each IDOD design are given in detail. Author
