Abstract:

This paper presents optimized hole shapes in plates of finite width subjected to uniaxial load for a large range of hole to plate widths DW ratios. The stress concentration factor for the optimized holes decreased by as much as 44 when compared to circular holes. Simultaneously, the area covered by the optimized hole increased by as much as 26 compared to the circular hole. Coefficients of efficiency between 0.91 and 0.96 are achieved. The geometries of the optimized holes for the DW ratios considered are presented in a form suitable for use by designers. It is also suggested that the developed geometries may be applicable. to cases of rectangular holes and to the tip of a crack. This information may be of interest in fracture mechanics. Auhtor
